Compare localSheetId it uses sheet index instead of sheet's sheetId

This improves compatibility for absolute XML path, Windows-style directory separator and inline namespace;

lint issue fixed and new formula function: ATAN, AVERAGE, AVERAGEA, CONCAT, CONCATENATE, COUNT, COUNTBLANK, MAX

- correct adjust calculation chain in duplicate rows
- correct adjust defined name in the workbook when delete worksheet
- use absolute reference in the auto filters defined name to make it compatible with OpenOffice
- API `CoordinatesToCellName` have a new optional param to specify if using an absolute reference format
- Fix cyclomatic complexity issue of internal function `newFills` and `parseToken`

* optimize marshal

* optimize mem alloc

* add benchmark testing

* add NewSheetWithRowNum testing

* sync struct fields order

* add BenchmarkNewSheetWithStreamWriter

* delete NewSheetWithRowNum and benchmark test

This closes #714 and closes #715, fix wrong worksheet index returned by NewSheet in some case, fix panic on formatted value with no built-in number format ID

- Update unit test

Default row height compatibility with Apache OpenOffice and Kingsoft WPS, unit test update and typo fixed

- typo fix, resolve #635
