modified endpoints and advance_endpoints so that REGBRIDGE_OFFSET end…

[lucask07]

The "roll over" feature of advance_endpoints was acting on REGBRIDGE_OFFSET bit indices when it should not. REGBRIDGE_OFFSET bit indices should always advance with the chip number independent of the MAX_WIDTH.

Modifications:

• Add a regbridge boolean to the Endpoint class that detects if _REGBRIDGEOFFSET is in the endpoint name.
• in advance_endpoints check for not endpoint.regbridge before "rolling over" the bit_index_low and the bit_index_high.
• Note that the endpoint address is irrelevant to how we right to the register bridge.
