feature request for support branch.sort

[lucidash]

gitui seems to support default order(lex-asc) by branch name only.

It will be very helpful when support options to change branch.sort config
(e.g. git branch --sort -committerdate)

[extrawurst]

as for almost everything in git implementing this like git does is very complex - for reference:

• https://git-scm.com/docs/git-config#Documentation/git-config.txt-branchsort
• https://git-scm.com/docs/git-branch#Documentation/git-branch.txt---sortltkeygt
• https://git-scm.com/docs/git-for-each-ref#_field_names

my suggestion is:

adding a sort option popup that allows sorting to be changed between the following keys:

• refname
• last commit timestamp
• last author

at the same time we should probably also show the last commit timestamp in the table
