stm32flash write protected #70

Hello! Great software. Thank you for it. I was trying to use this: https://github.com/jeanthom/DirtyJTAG/blob/master/docs/install-bluepill.md

And I needed to unprotect my stm32 with this commands first. I think it would be helpfull if you put them in the doc because people are using the vendor propietary sofware for windows to unlock because then don't know stm32flash can do it. I almost use that software too.

If you get a NACK when trying to erase you need to remove write protection and if you get a NACK trying to make write unprotection then you need to remove read protection first. So I put the two commands.

stm32flash -k /dev/ttyUSB0
stm32flash -u /dev/ttyUSB0

Thank you again.
