Compiling with platformio cli

[Kilill]

Just a suggestion for the platformio build instruction.

Since i usually just use the platform io cli from a console the instructions for compiling and and uploading from the command line. it of course presupposes that the platform cli is available , preferably also included in the PATH env variable...

Compile source pio run Build file system from data directory pio run -t buildfs Upload code image pio run -t upload Upload filesystem image pio run -t uploadfs
