[src/core/fonts.js] Replace some unnecessary Stream.getUint16() calls with Stream.skip(2) instead

Browse Source 
There's a handful of cases in the code where the intention is simply to advance the `Stream` position, but rather than only doing that the code instead fetches/computes a Uint16 value (and without using the result for anything).
