Add FeatureDescriptor and input/output StepCount

[heavyrubberslave]

When I wanted to upgrade to v4 of this library I realized that some information is not exposed anymore, namely a descriptor of the feature and the step count.

I needed those to give the features a proper label in the UI and to make the slider jump the right amount (min: 0, max: 100, stepCount: 25 = 5 slider positions: 0, 25, 50, 75, 100).

In v3 I access them like this:

device.messageAttributes.ScalarCmd[0].FeatureDescriptor
device.messageAttributes.ScalarCmd[0].StepCount

Is this information not accessible on purpose? If not, then I'm happy to make a PR to expose it again.

Oh, shit, yeah, we're missing exposure on those. They do exist, they're just not accessible. Mistake on my end.

I'll try to get that updated, but you may also want to look at https://www.npmjs.com/package/@zendrex/buttplug.js which takes a different approach to the API exposure and looks more like the last version of the library.

Created the PR: #304

@qdot thanks for releasing the new version 🙂

Just one issue with the inputs. I get this for my Hush:

 _events: {}
    _eventsCount: 0
    _deviceInfo: {
      "DeviceFeatures": {
        "0": {
          "FeatureDescription": "",
          "FeatureIndex": 0,
          "Output": {
            "Vibrate": {
              "Value": [
                0,
                20
              ]
            }
          }
        },
        "1": {
          "FeatureDescription": "battery Level",
          "FeatureIndex": 1,
          "Input": {
            "Battery": {
              "Command": [
                "Read"
              ],
              "Value": [
                [
                  0,
                  100
                ]
              ]
            }
          }
        }
      },
      "DeviceIndex": 2,
      "DeviceMessageTimingGap": 100,
      "DeviceName": "Lovense Hush"
    }

The problem is, that for the battery input it's a nested array with ranges. But the type definition says it's just ButtplugClientDeviceFeatureValueRange not ButtplugClientDeviceFeatureValueRange[]:

export type ButtplugClientDeviceFeatureValueRange = readonly [
    min: number,
    max: number
];
export interface ButtplugClientDeviceFeatureInput {
    readonly type: Messages.InputType;
    readonly valueRange: ButtplugClientDeviceFeatureValueRange;
    readonly commands: readonly Messages.InputCommandType[];
}

sigh this is why I really gotta finish out our cross client compliance testing. :(

I'll have 5.0.2 out later today.
