Feature request: string pad

[pmlandwehr]

Would it be possible to get a string pad function to complement string trim? I realizing that padding can effectively be accomplished using things likeprintf "%<n or negative n>s\n" $strs_to_pad | tr " " "<padding char>", but it seems like a natural extension.

I'm at fish, version 3.1.2 on Mac OS X

I made an attempt to implement that. It works like that (from my build directory):

❯ ./fish -c "string pad -l -r -n 10 --chars c test"
cccccccccctestcccccccccc
❯ ./fish -c "string pad -l -n 4 --chars ' ' foo"
    foo

I would be thankful for guidance on making this into upstream.
