v1.8.0

Features

• Added support for text alignments. Alignments are specificed using the Alignment property on a Style object.
• Added support for hiding worksheets by setting WorksheetOptions.Visibility.
• Added support for absolute references in data validations. Can now use for example $A$1:$A$5 as a cell range.
• Added an option to get the next row number from the active worksheet with Spreadsheet.NextRowNumber.
• Added overloads for AddRowAsync which takes ReadOnlyMemory<T> of cells and RowOptions.
• Updated Spreadsheet.FinishAsync to also flush the resulting archive. This should prevent a partially corrupt XLSX file if the XLSX file is being used before the Spreadsheet is properly disposed.

Breaking changes

• The Style class and related style classes have changed to become records.
