if a port needs 2.x then set MODPY_VERSION=${MODPY_DEFAULT_VERSION_2}.
This commit doesn't change any versions currently used; it may be that
some ports have MODPY_DEFAULT_VERSION_2 but don't require it, those
should be cleaned up in the course of updating ports where possible.
Python module ports providing py3-* packages should still use
FLAVOR=python3 so that we don't have a mixture of dependencies some
using ${MODPY_FLAVOR} and others not.
The utility supports editing multiple MP3, Ogg/Vorbis, FLAC, MPC,
MP4/AAC, MP2, Opus, Speex, TrueAudio, WavPack, WMA, WAV and AIFF
files at once, having full control over ID3v1 & v2 tags. There are both
GUI and interactive CLI.
