v2.5.0 Adding tabularray

This release has a major update of replacing the default array package with the new tabularray package.
Of the many improvements this package brings, it allows for auto-sizing columns and sensible vertical alignment.

Most columns have the same default behaviour, however the following additions have been made

• Capital columns (i.e. L{<width>}, C{<width>}, etc.) can take multiple arguments, including a vertical alignment option.
• List columns (i.e. I{<width>} and E{<width>}) have an optional argument to pass options to the enumerate environments.
• Cells in list columns that do not start with \item will not be typeset as columns.
