Update to Micropython V1.13

[Susan Mackay]

I have updated to the latest firmware for my LoPy4 board (1.20.2.r3) but the Micropython version is V1.11.
The latest Micropython version is V1.13 and it contains the 'uasyncio' module that I would like to use for my new project.

1. Is there some way to upgrade the Micropython version myself?
2. If not then is there a roadmap for when the PyBytes firmware will include V1.13?
