Captures lookup of all the AAT tables into a new type and builds them directly from table data rather than going through ttf_parser::Face.

This will allow us to remove ttf_parser::Face from hb_font_t before AAT support in read-fonts is done and will enable us to replace those tables one at a time.

Builds on #10

Replace `ttf_parser::Tag` with `font_types::Tag` throughout the code.
