Expand 'make monitor' support New 'make monitor' idf_monitor tool for better monitor output. Running 'make monitor' will now: * Automatically look up code addresses via addr2line and print function, source file, line number in terminal. * Can reset the ESP32 by typing Ctrl-T Ctrl-R. * Can run "make flash" by typing Ctrl-T Ctrl-F. * Can run "make app-flash" by typing Ctrl-T Ctrl-A. * If gdb stub starts, monitor will automatically run gdb and connect. When gdb exits, ESP32 resets and monitor resumes. * Exit is still Ctrl-[ Have some more features I'd like to add (log output to file, crash dump support) but I think this is at the point of being useful.
