Hi and thanks for a great tool set.

I've implemented a faster FM demodulator for rlt_fm. Its an instantaneous frequency demodulator, like the already implemented atan method, but it uses some math tricks to get rid of the the actual atan calculation. Feel free to use it if you wish

Nice, thank you.

It should probably be under the -A option with all the other types of FM demodulator math. Maybe benchmark it against the other FM demodulators, "-A fast" or "-A lut". The default "-A std" was not designed to be very quick, just accurate. Being faster than "-A std" is not very difficult.

Let me see if I can get a fixed-point version written.
