Strip the stdio integration from FastSerial as we aren't using it and it just wastes space.
Note that this does not attempt to fix the bogus floating point handling in ::print(ln). That's an issue for another day.
BetterStream::printf(_P) aka FastSerial::printf(_P) support is now as documented for avr-libc printf with floating point support enabled.
