waf config outdated & unusable

[binury]

Hopefully this saves someone a few hours of troubleshooting waf needlessly…

the waf version included in the repo is so old that the syntax of File.open (mode) used is no longer valid… (at least before python3.11)

❯ lossywav-for-posix master* python3 waf configure

ValueError: invalid mode: 'rUb'

downloading a newer waf (2.X ?) resolves this issue

But waf's config api appears to have also changed and it is unclear whether these tests actually pass

In any case, waf build will fail

Despite all this, building directly with the makefile is successful 🎉 .

Thank you for reporting. waf builds should work now.
