Bug: Aspect registers request error

Created by: drewbotts

The Aspect driver correctly requests for the number of registers and uses that value to query for data. But, the Aspect hardware seems to not always give a correct response (i.e. says it has 64 when it doesnt).

Possible solution: set the data request to register 100 with a word count of 21 (registers 100-120 contain the readings from the detectors).

future research: when available, test out other queries to see if aspect give correct number of registers to request.
