Browse Source 
* use RLE encodes bitmaps on 212x64 pixel radios

* fix model image display
fix icon display

* implement RLE bitmaps in companion for splash image on 212x64 radios
reserve 3kB for RLE bitmaps in firmware

* fix size check

* use defines instead of magic numbers

* fix display of splash screens on 212x64 radios

* add warning message if compressed image is larger than the reserved space
