Update the heating code to periodically check that the main thread is operating properly. This is a mitigation for some rare cases where the main thread may lockup while the background heater updating code continues to run. The goal is to detect these rare failures and disable future heater updates. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
