Re-implement filter inspection

[Karlo-Emilo]

We have the current implementation, which can be seen on ml-machine.org/.

We also have Nicolai's prototype of a new, more interactive inspection tool: https://gitlab.au.dk/au-cs-ceed/ml-microbit-browser/-/tree/filter-inspection

It may be too time-expensive to finish Nicolais prototype, but we may be able to make a simplified version

This task includes some design work and decisions.

Do #95 first.

Do this before #96

[Karlo-Emilo]

Status:

A first draft has been implemented in #264

The following needs to be implemented before this feature can be production ready:

• Add navigation to this feature from the Trainer page as suggested in Add proper way to navigate to filter page #239
• The live data in the plots should be the respective filter.output not the raw output from the accelerometer
• Disable the extra inspection of the filters. currently, you can clack the filters for extra details (in Filter inspection details partial #264 ). This should not be implemented in this first round.
• The plots should not show bars, but the raw data points (preferable) or box-plots or similar.
