Use BOOT1 as bootloader enter button in bluepill board. #21

The bluepill board has a dip-switch connected to BOOT1 (PB2) via a 100k resistor.

This allows entering the bootloader when connecting the switch to "1".

Looks good to me. I tried it out on my bluepill board that has jumpers on BOOT0/BOOT1 and removing the jumper connecting it to 0 was sufficient to enter the bootloader. Thanks for the contribution!
