EmonSD build script progress update and beta release

Wifi AP setup and switching to client mode are now working as expected. A number of changes to the wifi module and setup module have been made to improve functionality.

The update process is working.

The build script has been tested to work with the RaspberryPi 4 & Buster.

My personal test of a system built using the build script is running along nicely. My OS partition and logs write load is 12 sectors/minute (0.1 kb/s) which is similar to what I reported in earlier testing. The data partition write rate is ~40 sectors/minute (0.33 kb/s) that’s with a buffered write to disk at 5 mins interval.

I’ve created an issue on the EmonScripts repository with my logrotate results:
