This change allows transcoding new UASTC .basis files to BPTC which
results in much higher quality compared to UASTC -> BC3 transcoding.

The change needs to introduce BPTC support to three.js core for this to
work; the format is introduced in EXT_texture_compression_bptc which is
available in Chrome Canary on Windows (and possibly elsewhere?)

The update to Basis transcoder just pulls it directly from Binomial
repository; the transcoder is a bit larger now, unfortunately, because
it needs to support UASTC.

Note that we use mode 5 unconditionally to make sure RGB and RGBA
textures work.

BPTC (BC7) and BC3 are the same size in memory so this shouldn't
negatively impact VRAM consumption.
