Feature Idea: Include the buttplug protocol and identifiers for quick mapping to capabilities

[blackspherefollower]

There's aspects of the device capabilities that are not exposed in IoSTIndex: the details on the levels of control per feature. Whilst I mad some attempts to indicate where a capability is remotely controllable, I didn't duplicate things like step counts. But since the buttplug protocol name is already in the data, adding the identifier would allow for fast cross referencing to display more advanced details.
