Rust bootloader

[MabezDev]

We currently use the C bootloader used in the arduino sdk core (slightly modified for PSRAM support). We should be able to write an equivalent in Rust.

Agree, however to add some color: it is quite a major task: the bootloader initializes flash, ram (depending on board and efuse config), memory protection unit; then it loads the partition table and loads the various segments to the correct places. Finally it sets up the caches correctly and hands over to teh user program.

I agree this is a lot more complicated than it sounds. I'd say this is more a stretch goal, than something we should actively working on now.

We can also think about using mcuboot instead of the IDF bootloader.
