Running REPL in thread may solve some issues with uasyncio
and long running or infinite loops
Updated 'machine.UART' module
- fixed bug when wrong parameter was returned to callback functions
- added option to set inverted mode for Rx, Tx, CTS, RTS
- enabled using hw flow controll if CTS and/or RTC pisn are defined
- 'write_break()' function added whitch enits the break signal after data write
Updated 'sys' module
Added 'sys.tz()' to get or set the time zone
The time zone is saved in NVS string and time zone is set on boot
The time zone can be now preserved on reset, power off or deepsleep wake up
Updated 'machine' module
Added SetStackSize() function to set the MicroPython stack size
Added SetHeapSize() function to set the MicroPython heap size
Both heap an stack sizes are set as NVS variables and are read at boot time
to set the sizes, so the sizes may now be different than the compiled ones
Updated 'machine.timer' module
Changed function name 'reshot()' -> 'reshoot()'
