[Elecraft] K2 Autospace keying

And I hope it can be added to the KX1 firmware as well.

IMHO, once you get used to the auto character space feature, it is hard to
go back to a keyer without that option.  That is why I still use the
original CMOS Super Keyer 1 from the 1980's.  Like the WB4VVF Accukeyer, it
allows smooth sending at higher speeds with great timing. The NorCal Keyer
and the K1EL chips also have that feature.
