This package was failing to build because of some missing dependencies.

Upstream added a new dependency on PyYAML in v0.4.1:
https://github.com/googlefonts/shaperglot/commit/94a9b30ec0f928851700ca9d3efa5d3d0aef1661
and switched from poetry to setuptools in v0.4.2:
https://github.com/googlefonts/shaperglot/commit/2c76ffa082a2bebb2a0f5bc491e37804091a1aec
