Type-1 subsetting
This reduces pdf file sizes when usetex is active, at the cost of some complexity in the code. We implement a charstring bytecode interpreter to keep track of subroutine calls in font programs. Give dviread.DviFont a fake filename attribute and a get_fontmap method for character tracking. In backend_pdf.py, refactor _get_subsetted_psname so it calls a method _get_subset_prefix, and reuse that to create tags for Type-1 fonts. Mark the methods static since they don't use anything from the instance. Recommend merging to main to give people time to test this, not to a 3.10 point release. Closes #127.

When using the PDF backend with the usetex feature,

Matplotlib calls TeX to render the text and formulas in the figure.

The fonts that get used are usually "Type 1" fonts.

This reduces the size of the resulting PDF files.
