configs: add command-line option to stop debug output
This patch adds a --debug-end flag to main.py so that debug output can be stoped at a specified tick, while allowing the simulation to continue. It is useful in situations where you would like to produce a trace for a region of interest while still collecting stats for the entire run. This is in contrast to the currently existing --debug-break flag, which terminates the simulation at the tick.
