Possibly remove ADC_CONFIG write in ConfigureNeuropixelsV2e.cs

[jonnew]

The Neuropixels 2.0 system developer docs have been released. They state that register 3 is reserved and not to be used. However, we are writing to this register because it was required by the beta variant of the probe and we kept this configuration step when moving to the public version

I've tested removing this write and it does not seem to affect probe function. Should it be removed?

bonsai-onix1/OpenEphys.Onix1/ConfigureNeuropixelsV2e.cs

Line 323 in b9bdc3c

i2cNP.WriteByte(NeuropixelsV2e.ADC_CONFIG, 0b0000_1000);

With this register write removed, I'm seeing 8.5 uVRMS and calibrated 5mVPP signals through the probe in saline as specified on pages 14 and 43 of the user manual, respectively. The RMS is a bit high (2 uVRMS) however, its specified for the "AP band" in the manual. I don really know what that means. Maybe they are looking at 100 to 10 kHz or something? In any case, I think we can remove this.
