This pull request adds the feature Heartbeat Supervision. $SY , $GY as in
SY heartbeatinterval hearbeatcurrentlimit
If you do not send open_evse a heartbeat more frequently than every (uint16_t)heartbeatinterval seconds then open_evse will reduce system ampacity to (uint8_t)hearbeatcurrentlimit amperes

Testing still in progress.

Plays nice with TEMPERATURE_MONITORING. Compiles OK, but consumes incremental ROM and RAM. Testing still in progress.

This is good, clean code with clear comments. With an update to the PIO configuration (env_default is going away and it needed help recognizing the board file; PR submitted), it builds in PlatformIO.

Thanks for the PR. very nicely commented. i had to manually merge it, because your PR did weird stuff like replace whole files, probably due to the space characters getting replaced. i wish there were a way to get git to ignore those.

sorry again for the big delay
