[chirp_devel] Invalid version: 'py3dev' breaks build.

[Barry Jackson]

Dan,
I have looked at the latest daily tarball and building from that I see 
the same error, albeit with another invalid CHIRP_VERSION as far as 
python3 is concerned.

packaging.version.InvalidVersion: Invalid version: 'next-20230126'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
   File "/usr/lib/rpm/pythondistdeps.py", line 626, in <module>
     raise RuntimeError("Error: pythondistdeps.py generator encountered 
an unhandled exception and was terminated.") from exc
RuntimeError: Error: pythondistdeps.py generator encountered an 
unhandled exception and was terminated.

I appreciate that 'n' is alpha-numeric and I have not read all of 
this[1], but unless this is fixed somehow it won't go away.
