The help text is now processed to generate a style array to pass to the
display_text library in addition to the text itself. The help text is still
compressed using LZ4, and still fits on the c200v2.

This is only really needed to save a few bytes on the c200v2, but
since it adds negligible overhead, so it's implemented for all
targets.
A stripped down version of the LZ4 reference implementation is found
in lz4tiny.c.
