channel index of NP 2.0 4-shank file

[Jiachen24]

Hello @mayofaulkner ! I am following up on the channel index of 4-shank NP 2.0 in file "channel_locations_shank1.json". All channels on individual shanks are indexed from 0 to 95. I couldn't find abovementioned additional key that reflects the actual channel index from the recording. This is mentioned in a closed issue as well #48

Hello,

I've made a change #133 such that the original channel index is now stored in the channels.location.json file e.g

{
  "channel_0": {
    "x": -191.9121944991095,
    "y": 2213.186990831849,
    "z": -4259.263416502671,
    "axial": -15.0,
    "lateral": 468.0,
    "brain_region_id": 814,
    "brain_region": "DP",
    "original_channel_idx": 240
  },
  "channel_1": {
    "x": -191.9121944991095,
    "y": 2213.186990831849,
    "z": -4259.263416502671,
    "axial": -15.0,
    "lateral": 500.0,
    "brain_region_id": 814,
    "brain_region": "DP",
    "original_channel_idx": 241
  },...

Please can you pull/ install the latest changes from the master branch of iblapps.

Let me know if you run into any problems
