PsychHIDGetIndexFromRecord()
The inverse of PsychHIDGetDeviceRecordPtrFromIndex.
This O(n) where n is the number of device elements. We could make it O(1) if we modified
the element structure in the HID Utilities library to include a field specifying the index of the element or
collection.
Note that if PsychHIDGetIndexFromRecord() is O(n) then its caller, PsychHIDGetCollections, is O(n^2) for each
device, whereas if PsychHIDGetIndexFromRecord() is O(1) then psychHIDGetCollections becomes O(n) for each
device.
