[time-nuts] Adding prescaler to HP 5334B

The diode limiter is to protect the C channel
from getting burned out due to connecting a
transmitter to it, etc.  You don't need the
limiter if you aren't worried about this.
The detector gates off the counter when there
is insufficient signal to count reliably.
The detector is imperfect, and the counter
may read garbage anyway, or may be blanked
on a signal that would be countable.  For the
average time nuts user, you can leave out both
of these "features" with no harm.  I had to
design them in for "marketing" reasons.
