Hi, some use cases i could not complete because did not find micropython equivalent for those on unix-android/ esp8266

sys.excepthook:

• restore terminal sane settings on failure when using picotui.
• reset boards to safe state on emergency.
• remote debugger/IDE helper ( transmit filename / line / msg )

sys.displayhook:

• allow infinite repl enhancements. ( xonsh shell like, pretty print etc ... )
• and simple stdout multiplexing/filtering hacks when using coroutining or extra displays.
