Hiero: Effect Categories - OP-7397

[tokejepsen]

Changelog Description

This PR introduces Effect Categories for the Hiero settings. This allows studios to split effect stacks into meaningful subsets.

Testing notes:

1. Setup Effect Categories in Hiero addon settings (see documentation).
2. Setup a clip in Hiero with effects corresponding to the settings.
3. Publish clip and effects.
4. Load into Nuke and verify the effects are grouped correctly.

awesome work! Can we also add default values as you were showing in documentation into the variable DEFAULT_PUBLISH_PLUGIN_SETTINGS?

[jakubjezek001]

Also it seems like the exported effects json is not correct. In my case it had published the contect like this a01vfxd_sh010_effectPlateP01Look_v001.json

{
    "assignTo": "plateP01"
}

Timeline effects

Publisher instances are correct

Conclusion:
It is not collecting soft effect nodes and then those are not serialized into json files.

I would maybe argue that we should not have any defaults to maintain backwards compatibility?

@jakubjezek001 I'm not entirely sure what you meant here, but I've fixed the case where effects are not categorized, in which case we just dump the effects into the "main" effects.

Once the suggestion is implemented anyhow, then it is good for merge.
