Previsous version had some bugs. Bugs fixed plus modified FSM by removing temp_rise processing from FSM and generating it from separate process.

Implementation post-review. Main changes are to pull the falling and rising edges of the asynch pulses directly from the conv_pulse_gen module as outputs and input those the burst controller. The top files have been modified accordingly. Also the pulse output now is correctly generated at the poutput port depending on PCB version and pulse width selection

Now using an FSM to hadel pulse repetition and rejection. Thermal model constant decrement steps are now a generic rather than a signal

Updated top file and burt control module with little modifications. NOTE LED sequence is fixed at certain pattern for bitstream debugging
