this version has several enhancements, such as doubling text writes to display which were slow and improving the draw performance of the color bar, and significant performance boost of the graphics showing of the upsample amg8833 thermal sensor output.

i also now turned off debug serial for display block time updates. this should speed things up more. sending a capitol 'C' to Arduino serial will send a copy of 8x8 sensor output. 

here is it in action.
