Describe your issue

The following error is thrown during build:

ERROR: Could not find a version that satisfies the requirement lameenc (from versions: none)
ERROR: No matching distribution found for lameenc
Chaquopy: Exit status 1

FAILURE: Build failed with an exception.

The package lameenc is required by demucs (https://github.com/facebookresearch/demucs). Would it be possible to add support for it?
