Automatically generate .uf2 files anytime we generate a .hex file for…

… nrf52 (#4370) * Automatically generate .uf2 files (which are often used by nrf52 bootloaders for installing app loads) anytime we generate a new hex file. This tool takes very little time to run and it is handy for development * Remove an old custom target I had tried to add to autogen uf2 files (that never worked) Build output now looks like: $ pio run --environment tracker-t1000-e Processing tracker-t1000-e (board: tracker-t1000-e; platform: platformio/nordicnrf52@^10.5.0; framework: arduino) ... Generating UF2 file Converting to uf2, output size: 1395200, start address: 0x27000 Wrote 1395200 bytes to /home/kevinh/development/meshtastic/firmware/.pio/build/tracker-t1000-e/firmware.uf2 Building .pio/build/tracker-t1000-e/firmware.zip Zip created at .pio/build/tracker-t1000-e/firmware.zip =================================================================================== [SUCCESS] Took 9.33 seconds =================================================================================== Environment Status Duration --------------- -------- ------------ tracker-t1000-e SUCCESS 00:00:09.327 =================================================================================== 1 succeeded in 00:00:09.327 =================================================================================== Co-authored-by: Ben Meadors <[email protected]>
