fix: make available(pipe) depend on available(void)

[2bndy5]

I've been code golfing in rust again...

By making available(pipe) call available(void), we can get the same behavior without instantiating a dummy byte (RF24_FETCH_NO_PIPE) . This way available(pipe) also doesn't need to check the pipe parameter's value; it just mutates it because that is the overload's purpose.

This should decrease the compile size in general, more for any app that doesn't actually call available(pipe).

This should decrease the compile size in general

Odd, there's a 4 byte increase in flash on ATSAMD21 for the examples that use available(pipe). Luckily, that's still negligible for that chip. The changes in ATMega328 flash consumption are all favorable as expected.
