bltool.py: flashing utility

Command line arguments

Argument	Description
-p / --port	The serial port to use
-b / --baudrate	the baudrate to use (default: 115200)
-i / --info	Print OTP info
-e / --erase	Erase the flash chip
-w / --write	Write to the flash chip. Usage: -w address filename
-r / --read	Read from the flash chip. Usage: -r address length filename
-v / --verify	Read back after writing to verify the resulting flash state

Notes

Always erase the flash before writing, this is needed because of how flash memory works
A baudrate of 115200 works, higher baudrates seem to work but can cause verification errors
Needs pre-processed binaries to work, this tool currently does not add the required boot headers
