Comment 3 for bug 2047149

@Didier, I've clarified the testing story, the codec will be (lightly) tested through the roc-toolkit tests (which is the component consuming the library). I've also added a section to https://wiki.ubuntu.com/DesktopTeam/TestPlans/Pipewire for manual testing coverage.

Also note that the speexdsp code had been in main as part of speex until jammy as mentioned in the description which probably means it can do with a lighter review
