Add Bearing Fault Detection (UORED) example akida1

[dmclellandbc]

This PR integrates a new Akida 1 model for Bearing Fault Detection (1D time series vibration data), using the UORED-VAFCLS dataset.

Two performance metrics are presented, to highlight a systematic methodological flaw in the evaluation of models on this (and related) datasets.

Two TODOs remain beyond this PR:

• Data file to be hosted on Brainchip server
• Training and Benchmarking notebooks (as per example template) to be added. Committing without these in the first place in order to make the model available for internal technical evaluation.

Good one,
Mainly rewording of docstrings.
One question about the actual input shape worth checking: comment showed (1200, 35) but the code said (300, 140), so I assumed that was the correct one.
I feel like a lot of information is currently "hidden" in each file's docstring, so it's a bit hard to follow, but I am assuming this will be resolved by the soon to be notebooks.
