When we are given a with that is larger than the content we have,
expand the space between columns, within reason. We only make the
table at most 1.5 times as wide as it would be unexpanded.
Add a new API for setting individual columns to expand (or not).
For an expanding column, we'll grow the space between it and its
preceding column. The expand flag of the first column is ignored.
By default, columns do not expand.
Make flatpak_table_printer_print_full return not just the table
height, but also the width.
Update all callers.
