etcpak 0.6

A new version of etcpak has been released. There are a couple of small changes in 0.6, but the main one is newly added support for compressing ETC2 RGBA textures.

Example compression result (only showing alpha channel):

16K x 16K image benchmark:
ETC1: 113 ms (only RGB part)
ETC2 RGB: 213 ms (only RGB part)
ETC2 RGBA: 404 ms
