Default DSP should be set to off in ConfigureRhd2164

[jonnew]

For some reason, the default value for the DSP setting in ConfigureRhd2164 is set to 0.146 Hz.

bonsai-onix1/OpenEphys.Onix1/ConfigureRhd2164.cs

Line 55 in 7fb9332

public Rhd2164DspCutoff DspCutoff { get; set; } = Rhd2164DspCutoff.Dsp146mHz;

It should be set to off to match the analog settings, which default to the widest pass band possible.
