refactor: embed Liberation Mono as a WOFF file, upgraded to 2.1.5

Replaces the 238KB base64 string literal with a go:embed of the
WOFF binary; FontLiberationMono is now encoded at init and keeps
its exported name and type.

The WOFF is converted losslessly from LiberationMono-Regular.ttf
in the official liberation-fonts-ttf-2.1.5 release tarball (the
foundry publishes no WOFFs). Every sfnt table in the WOFF is
byte-identical to the release TTF, checksums included. This also
replaces the previous font data, which came from an intermediate
2.00.5 build with incorrect post-table metadata (isFixedPitch=0,
wrong underlinePosition).
