This is an initial implementation of a parser for the WOFF2 font packaging format. It is incomplete; further work will come later. The scope for this milestone was to be able to parse .woff2 files for the needs of the github.com/ConradIrwin/font/sfnt package. At this time, the API is very low level and maps directly to the binary format of the file, as described in its specification. This API is in early development and is expected to change as further progress is made. It successfully parses some Go font family .woff2 files that were generated using the https://github.com/google/woff2 encoder from the Go font source .ttf files located at https://go.googlesource.com/image/+/master/font/gofont/ttfs/. Add basic test coverage. Helps https://github.com/ConradIrwin/font/issues/1.
