Quick function for one-off high pass filtering. If repeated lowpass filtering is needed, first design the required filter using design_lowpass_filter, and then use FIRfilter to do the actual filtering.

Parameters:

in_sig - input waveform, which will be overwritten
- freq cutoff frequency in Hertz
order - number of filter coefficients, eg. 99
