hplip: incompatibility with python3.10

[alandiwix]

See https://bugs.launchpad.net/hplip/+bug/1933973
There are several issues in hplip codebase, the one I encounter personally is:

Scanning...
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python3.10/threading.py", line 1009, in _bootstrap_inner
    self.run()
  File "/usr/share/hplip/scan/sane.py", line 548, in run
    st, t = self.dev.readScan(readbuffer)
SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats
Reading data: [\       

The error

SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

is common among those. Some other distributions managed to solve that, Fedora's patch for example:
https://launchpadlibrarian.net/546031954/hplip-pyssizet_clean.patch
Is it possible to do the same in Void?

Sure! Would you like to make a PR yourself or should someone else look into fixing it?

bump hplip to 3.21.8,
@alandiwix I can run some test, use it at work but not noticed any issues while scanning.. will look into it

[biopsin]

@alandiwix I use xsane to scan so I can't reproduce the issue.
What args are you passing with hp-scan command?
I noticed hp-scan complains of missing python-image-library (PIL), so the template needs reviewing.
And also latest version need ajust for ../prnt/hpcups/libImageProcessor*.so
Ok I'll look at again.

@biopsin hp-makeuri 1.2.3.4 does it for me

[biopsin]

I'll test it again tomorrow

[biopsin]

Tested current hlip version with patch and the error is fixed, moving forward with hplip to latest release.
I also need to fix a makefile as "libImageProcessor-x86-XX.so" is not being picked moved up upon install

[biopsin]

@ericonr a notice here , as they continue ship nonfree blobs, we should continue distribute a amputed version or move to nonfree?

Some log&issues

[alandiwix]

@ericonr would be nice if someone else could fix this.
I don't have too much experience with either void build system or python.
