/// This macro is an helper to create pin easily. You can create your pins by the name they have on
/// the little flyer you got when you bought your teensy. You can create your pin with name like:
/// ```rust
/// let pin = make_pin!(led);
/// let pin = make_pin!(23);
/// let pin = make_pin!(A8);
/// let pin = make_pin!(TX2);
/// let pin = make_pin!(DOUT);
/// let pin = make_pin!(SCL0);
/// let pin = make_pin!(PTD3); // from the schematic view
/// ```
/// You can also call this macro with multiple arguments. In this case it'll generate a tuple:
/// ```rust
/// let (pin5, led, tx, a8) = make_pin!(5, led, TX3, A8);
/// ```
