First draft of new BSP interface. SIL is working,

all other BSP drivers are broken for now.

add publish of capabilities for runtime changes

add MREC fault types for EvseManager and bsp interface

add more specific error codes for connector lock.

support A_63_3ph_70_1ph

add separate pp_ampacity var

add draft for connector lock interface

Allow non IEC compliant EVs to pause/resume

Start adding error definitions. SIL is still waiting for JS support for errors

Add errors for evse_manager

allow resume charging after everest restart

remove extra stop power on unplug. This may lead to a short pause state if C->A happens without going through B

move connector_type into hw_caps
