Re-adding snapweb into Debian's snapserver package

[MichaIng]

I recently recognised and wondered why Debian does not include snapweb into their snapserver package. Reason is that the used libflac.js library was an own copy, without proper source code, in the past, as can be read in the package changelog: https://metadata.ftp-master.debian.org/changelogs/main/s/snapcast/unstable_changelog

This however has changed last year: #46

So Debian could re-add snapweb again.

I could open a PR or Debian bug tracker issue about this. Should be actually quite simple, removing:

• https://salsa.debian.org/debian/snapcast/-/blob/master/debian/not-installed
• https://salsa.debian.org/debian/snapcast/-/blob/master/debian/patches/disable_snapweb.patch
• https://salsa.debian.org/debian/snapcast/-/blob/master/debian/patches/series#L1

I just wanted to check back, whether there were efforts regarding this already, or whether it makes more sense to have this done by Snapcast developers themselves.
