refactor!: Improve interactive correlation plot

[ramyamounir]

This PR is now ready for review (@nielsleadholm) but it is branched off of PR#15, so it should be reviewed only after PR#15 has been merged and the updates are pulled. Therefore, I will keep it in draft mode for now.

This PR introduces many changes including:

• TBP color palette as part of the interactive library to be used in all plots.
• A PretrainedModelsLoader which simplifies the process of loading a Monty pretrained model as a point cloud object in Vedo.
• A ScopeViewer which defines scopes for visibility. The user defines a list of scopes for each widget, then toggles the scope visibility with keypresses (e.g., 1, 2, or 0 for all scopes)
• Allowing Events to be detected as part of the WidgetUpdater, Which is useful for adding many more features without having to add buttons/sliders for them.
• The ability to expire topics from the widget updater inbox. By default, a widget updater will keep a list of watched topics values in its inbox and send the full inbox (with latest values of each topic) to the callback. Sometimes, we want to remove a topic from the inbox. For example, events (e.g., key press) are likely to be expired after we use them once.
• A new Top-K slider that shows multiple high evidence hypotheses at the same time.
• Agents and sensor paths toggled with key presses. Very useful for debugging and explaining Monty.
• Transparency of meshes now change with left and right arrows key presses.
• Other (stylistic) fixes and renames.
