Make CTCSS tone squelch block.

Parameters:

rate	gain of the internal frequency filters.
freq	frequency value to use as the squelch tone.
level	threshold level for the squelch tone.
len	length of the frequency filters.
ramp	sets response characteristic.
gate	if true, no output if no squelch tone. if false, output 0's if no squelch tone.
