There is a new pull request by mhmdanas against master on the void-packages repository

https://github.com/mhmdanas/void-packages mupdf-1.19.1
https://github.com/void-linux/void-packages/pull/37004

mupdf: update to 1.19.1.
I also switched from a `tar.gz` tarball to a `tar.xz` one since it's
smaller in size (87 MB vs 62 MB).

#### Testing the changes
- I tested the changes in this PR: **briefly** (I tested the `mupdf` command on a PDF file)


A patch file from https://github.com/void-linux/void-packages/pull/37004.patch is attached
