micro:bit v2 partial flashing

[PamoCurtis]

The upload over webUsb for the micro:bit v2 is not very fast, because the whole program will be uploaded every time which is very time consuming when working with larger programs. For this reason, partial flashing would be a great option to speed up the flashing process. Partial flashing compares all the pages of the micro:bit v2 and only flashes the ones that has changed since the last flashing process.
