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

[Dan Smith]

> If there was a URL like `https://trac.chirp.danplanet.com/chirp_next/latest` which either contained simple text or redirected to "https://trac.chirp.danplanet.com/chirp_next/next-YYYYMMDD/chirp-next-YYYYMMDD.tar.gz" that would really help out, at least from what I've seen with snap, flatpak and appimage building thus far.

The link on the download page almost does this:

https://trac.chirp.danplanet.com/download?stream=next

and will redirect to the build dir. You could pull the build name out of the URL it sends you to:

$ curl -Ls -o/dev/null -w '%{url_effective}' https://trac.chirp.danplanet.com/download?stream=next
https://trac.chirp.danplanet.com/chirp_next/next-20230127/

$ basename $(curl -Ls -o/dev/null -w '%{url_effective}' https://trac.chirp.danplanet.com/download?stream=next)
next-20230127
