Add function to handle a new input history record
This function will take a raw input power history
record and add it to the record manager cache.
The record manager will parse the raw record, validate
its sequence ID, and place it in the front of its
internal queue. It prunes its queue if it needs to
or clears it out if the sequence ID is out of order.
