Reduce texture memory usage for English speakersv0.10.0

We used to populate 7 4k textures + 1 2k texture for all users.
Now if the user has configured `bytes_per_char=1` in the Unity
panel, we just populate a single 512x512 texture containing the
first 128 ASCII characters.

This reduces texture memory usage by 99.74%, from 134.67 MB to
340 KB.
