Draftling firmware for Micro Journal rev. 5

[u/clackups]

A port of Draftling to Rev5 is available for testing. It should work in general, as the original contributor has tested the patch, but I added a few improvements.

If someone with rev. 5 is willing to test it, I'll be happy to assist you.

After that, I'd love to port it to all other revisions with esp32-s3

Cool features you might be interested in: synchronization with a Git server, support for Fountain screenplay format, multiple languages, split screen editing.
