v0.3

Add CPU utilisaiton indicator mode which will set the ring LED to green, yellow or red, based on the current utilisation %.

Thresholds are:
Green: <=33%
Yellow: >33% + <=66%
Red: >66%

Currently the CPU utilisation poll rate is hard coded to 2 seconds. Will make this and maybe the thresholds configurable at some point.

v0.2

New features:

• Add ability to disable the LED
• Add mode to cycle or fade through all the colours (experimental)

v0.1

Simple GUI to control LED colour and transition (fade/blink/solid)
