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.

Add print_P and println_P implementations to give folks wedded to the vanilla Stream methods a way to print PROGMEM strings.

Verified that when configured for 115200, the actual output as seen on a scope is around 117600Hz consistent with the +2.1% error in the datasheet.

At 115200 we expect ~100us between interrupts, or around 5% CPU overhead. 4us latency is probably acceptable for servo signal jitter too if we decide to consider using the Arduino Servo library.
