There's a merged pull request on the void-packages repository

maxima: update to 5.45.1.
https://github.com/void-linux/void-packages/pull/33309

Description:
Also:
- add rlwrap to depends so rmaxima (readline cli) works.
- add gnuplot to checkdepends, fixes 2 failing tests.
- add patch to allow more rounding, fixes 2 failing tests on musl.
- add rmaxima.1 and xmaxima.1 man pages as symlinks to maxima.1.
- do not compress info files, since they are used for in-program help
  and it doesn't work when they are compressed.
- add patch to copy test output to stdout, since it's too silent
  otherwise.
