all represents the 20 Fibers in a Feasa 20F, or 3 Fibers in a 3F.
0.xxxx represents the x Chromaticity value

Description
This command is used to return the xy Chromaticity value for the LED under the Fiber number
##. This command is used for testing White LED's.
This command should be preceded by a capture command to ensure valid LED data is stored
in the memory of the LED Analyser. The data for each LED can be read out one-at-the-time,
in any order. Note: it is important for the PC to use 01, 02, 03, etc to indicate Fibers 1, 2
and 3, etc.
Alternatively use the getxyall command to read back the LED data for all 20 leds in
one command.
Example:
The PC transmits getxy01 to the LED Analyser to instruct it to send the stored xy Chromaticity
data for the LED positioned under Fiber No 1. The LED Analyser will return a string 0.xxxx
0.yyyy to the PC.
getxy01
