LED rapid brightness update flicker

[dundalkian]

Describe the bug
A clear and concise description of what the bug is.
Rapid, effectively random changes to the LED brightness cause severe flicker at and above 100Hz

To Reproduce
Steps to reproduce the behavior:
Run 'output.py' to observe and alter parameters

Expected behavior
A clear and concise description of what you expected to happen.
It to not cause epilepsy, have a stable operating update rate that is well defined.

Additional context

• Find a reasonable upper bound to keep everything consistent (It still has some errors at 100Hz)
• Find the bottleneck causing this issue

The issue might have something to do with large, random jumps in brightness (i.e. 50 -> 200 -> 125). Whereas the slow, pulsing examples are only every iterating through possible values. Just a thought.
