0.301:
- Oopsie-release: The last one was missing PostScript names for the new glyphs.
  Only relevant for when extracting text from PDFs where the generator omitted
  the text stream.
- Rounded coordinates of macronbelowcomb.narrow and macroncomb.narrow.case.
  Leftovers from when they were scaled components.
- Internal: Removed stale layers and data, added normalization script to prune
  unnecessary data. import-glyphs.py also imports PostScript names now.
