BSDL: attach-bsdl command + persist the attached model

Browse Source 
New `attach-bsdl <module> <part> <file.bsd>` command: parse via BsdlModel,
apply_bsdl() onto the part, store the path on Part::bsdl_path, report bound/
unbound. Persist a `B\t<path>` line under the part; on restore, re-parse and
re-apply each attached model (the .bsd path is persisted, not the derived
pin specs). Round-trip covered by test_bsdl_apply.
