Watchdog Circuit Simulator - Fprime component

[RobertPendergrast]

Since we currently do not have a flight board, we need to develop a testbed to test the watchdog fsw component. Ideally, we'd want to emulate this with a separate piece of hardware (ie an RP2350) but until those arrive we can make an fprime component to do this.

• The emulator must have a timer that constantly counts down from a predetermined value
• We need an in port that connects to the watchdog emulator's outport
• When a signal is received on the in port we reset the counter.
• If the counter hits 0 we do a system reset.
