David Anderson 3a38cef8f9 jasper: remove, abandoned upstream.
Jasper has been marked insecure for a while, and upstream has not
been responsive to CVEs for over a year.

Fixes #55388.

# k2pdfopt is a pain to package. It requires modified versions of mupdf,
# leptonica, and tesseract. Instead of shipping patches for these upstream
# packages, k2pdfopt includes just the modified source files for these
# packages. The individual files from the {mupdf,leptonica,tesseract}_mod/
# directories are intended to replace the corresponding source files in the
# upstream packages, for a particular version of that upstream package.
#
# There are a few ways we could approach packaging these modified versions of
# mupdf, leptonica, and mupdf:
# 1) Override the upstream source with a new derivation that involves copying
# the modified source files from k2pdfopt and replacing the corresponding
# source files in the upstream packages. Since the files are intended for a
# particular version of the upstream package, this would not allow us to easily
# use updates to those packages in nixpkgs.
# 2) Manually produce patches which can be applied against the upstream
# project, and have the same effect as replacing those files. This is what I
# believe k2pdfopt should do this for us anyway. The benefit of creating and
# applying patches in this way is that minor updates (esp. security fixes) to
# upstream packages might still allow these patches to apply successfully.
# 3) Automatically produce these patches inside a nix derivation. This is the
# approach taken here, using the "mkPatch" provided below. This has the
# benefit of easier review and should hopefully be simpler to update in the
# future.
