T8b949e"""Make LXST Codec2 import optional so missing libcodec2 does not break telephony.

Upstream LXST 0.5.x imports Codec2 unconditionally in Codecs/__init__.py.

When pycodec2/libcodec2 is missing, that raises and prevents Opus profiles

and the whole Telephone stack from loading. Android wheels already soft-import

Codec2. This patch applies the same guard to a site-packages install.

Idempotent. Safe to run after every uv sync / pip install.
