Add --l2 plot option and extend summary info/plots with L5 offsets, L8 trims, and L9 MDP

[bbeny123]

This MR introduces two functional updates:

1. --l2 option for plot

Adds support for plotting based on L2 metadata.

• Before: plot generated plots using only L1 metadata.
• Now: plot --l2 generates plots using L2 metadata instead.

2. Extended metadata info in summary and plots

Additional metadata fields are now included in both the info -s and plot annotations:

• L5 offsets
• L8 trims (for CM v4.0 RPUs only)
• L9 MDP (for CM v4.0 RPUs only)

Examples:

Nice work @bbeny123!

Would it be possible to also add plot for L8 metadata (similar to L2 metadata, but for CMv4.0 instead of CMv2.9)?

And maybe others like L3 would also be nice, but this is less important.

Best regards and thank you very much!

[bbeny123]

Opened a new MR that goes beyond the scope of this one — it also adds plots for data related to the L8 metadata. If the new MR looks good, this one can be closed.

If it supersedes we can just close this.
