Addition of RSTOLONGN: this is the same function as RSTON but it is a pulse of 2ms.

Ben Todd explains: Allows the reset output to be connected to analogue circuitry on our main board.
200ns pulse is quite short for our application, so we have risk of SEU leading to spurious power cycles, and have quite a short RC-filter on the signal.
Could also be implemented as external hardware, but could mean additional logic which may not be used elsewhere in the design,
may need to be qualified in radiation.

Suggested RSTOLONGN pin: 95
