This made a refactor with breaking changes:

Motivation and Context

When I decided to add set horizontal centered support for this library to resolve #1358, the reason I made this huge breaking change was:

- There are too many exported types for set sheet view, properties, and format properties, although a function using the functional options pattern can be optimized by returning an anonymous function, these types or property set or get function has no binding categorization, so I change these functions like `SetAppProps` to accept a pointer of options structure.
- Users can not easily find out which properties should be in the `SetSheetPrOptions` or `SetSheetFormatPr` categories
- Nested properties cannot proceed modify easily

Introduce 5 new export data types:
`HeaderFooterOptions`, `PageLayoutMarginsOptions`, `PageLayoutOptions`, `SheetPropsOptions`, and `ViewOptions`

Rename 4 exported data types:
- Rename `PivotTableOption` to `PivotTableOptions`
- Rename `FormatHeaderFooter` to `HeaderFooterOptions`
- Rename `FormatSheetProtection` to `SheetProtectionOptions`
- Rename `SparklineOption` to `SparklineOptions`

Remove 54 exported types:
`AutoPageBreaks`, `BaseColWidth`, `BlackAndWhite`, `CodeName`, `CustomHeight`, `Date1904`, `DefaultColWidth`, `DefaultGridColor`, `DefaultRowHeight`, `EnableFormatConditionsCalculation`, `FilterPrivacy`, `FirstPageNumber`, `FitToHeight`, `FitToPage`, `FitToWidth`, `OutlineSummaryBelow`, `PageLayoutOption`, `PageLayoutOptionPtr`, `PageLayoutOrientation`, `PageLayoutPaperSize`, `PageLayoutScale`, `PageMarginBottom`, `PageMarginFooter`, `PageMarginHeader`, `PageMarginLeft`, `PageMarginRight`, `PageMarginsOptions`, `PageMarginsOptionsPtr`, `PageMarginTop`, `Published`, `RightToLeft`, `SheetFormatPrOptions`, `SheetFormatPrOptionsPtr`, `SheetPrOption`, `SheetPrOptionPtr`, `SheetViewOption`, `SheetViewOptionPtr`, `ShowFormulas`, `ShowGridLines`, `ShowRowColHeaders`, `ShowRuler`, `ShowZeros`, `TabColorIndexed`, `TabColorRGB`, `TabColorTheme`, `TabColorTint`, `ThickBottom`, `ThickTop`, `TopLeftCell`, `View`, `WorkbookPrOption`, `WorkbookPrOptionPtr`, `ZeroHeight` and `ZoomScale`

Remove 2 exported constants:
`OrientationPortrait` and `OrientationLandscape`

Change 8 functions:
- Change the `func (f *File) SetPageLayout(sheet string, opts ...PageLayoutOption) error` to `func (f *File) SetPageLayout(sheet string, opts *PageLayoutOptions) error`
- Change the `func (f *File) GetPageLayout(sheet string, opts ...PageLayoutOptionPtr) error` to `func (f *File) GetPageLayout(sheet string) (PageLayoutOptions, error)`
- Change the `func (f *File) SetPageMargins(sheet string, opts ...PageMarginsOptions) error` to `func (f *File) SetPageMargins(sheet string, opts *PageLayoutMarginsOptions) error`
- Change the `func (f *File) GetPageMargins(sheet string, opts ...PageMarginsOptionsPtr) error` to `func (f *File) GetPageMargins(sheet string) (PageLayoutMarginsOptions, error)`
- Change the `func (f *File) SetSheetViewOptions(sheet string, viewIndex int, opts ...SheetViewOption) error` to `func (f *File) SetSheetView(sheet string, viewIndex int, opts *ViewOptions) error`
- Change the `func (f *File) GetSheetViewOptions(sheet string, viewIndex int, opts ...SheetViewOptionPtr) error` to `func (f *File) GetSheetView(sheet string, viewIndex int) (ViewOptions, error)`
- Change the `func (f *File) SetWorkbookPrOptions(opts ...WorkbookPrOption) error` to `func (f *File) SetWorkbookProps(opts *WorkbookPropsOptions) error`
- Change the `func (f *File) GetWorkbookPrOptions(opts ...WorkbookPrOptionPtr) error` to `func (f *File) GetWorkbookProps() (WorkbookPropsOptions, error)`

Introduce new function to instead of existing functions:
- New function `func (f *File) SetSheetProps(sheet string, opts *SheetPropsOptions) error` instead of `func (f *File) SetSheetPrOptions(sheet string, opts ...SheetPrOption) error` and `func (f *File) SetSheetFormatPr(sheet string, opts ...SheetFormatPrOption

- New formula functions: MODE and T.TEST

ref #65, added new formula function: FINV

Preserve alternate content in the workbook, worksheet, and drawingML

* Fix show sheet tabs issue
* Ref #65, new formula functions: ERROR.TYPE, HOUR, SECOND TIMEVALUE

Added two exported functions `SetWorkbookPrOptions` and `GetWorkbookPrOptions` to support setting and getting the code name property of the workbook
Re-order fields of the workbook properties group to improve the compatibility
Go Modules dependencies upgrade
Put workbook related operating in new `workbook.go` source code
Library introduction docs block updated

Rename exported constants `NameSpaceDublinCoreMetadataIntiative` to `NameSpaceDublinCoreMetadataInitiative`

Go 1.15 and later required, #65 fn: IMABS, IMCOS, IMCOSH, IMCOT, IMCSC, IMCSCH, IMEXP, IMLN and IMLOG10

typo fixed

workBookRelsWriter, drawingRelsWriter into relsWriter;
drawingRelsReader, workbookRelsReader, workSheetRelsReader into relsReader;
addDrawingRelationships, addSheetRelationships into addRels

Add missing XML attributes `customWorkbookViews` and `customWorkbookView` in the workbook, relate issue #152.
