The new package sage-tdlib represents the old OptionalExtension sage.graphs.graph_decompositions.tdlib (building upon #29701, #28925). We use it as a second an example package for the modularization after sage-meataxe (#30151).

It does not use the incremental install mechanism of sagelib (sage_setup.command.sage_install.sage_install_and_clean). It uses a simple setuptools build system.

This is part of #29705: Meta-ticket: Modularize sagelib into separate distributions (distutils packages)

Depends on #34346
