Make use of lm75b temperature sensor optional.
Added papirus-radar demo showing the dependency of update rate on temperature.
This is a modified version of David Lowe's original demo (https://github.com/campag/eink-demo).
Best results with the modified epd driver from David Lowe (https://github.com/campag/gratis).
Will submit a separate PR to repaper/gratis repository with David Lowe's changes.
