Add support for node bundle sequences (e.g., time sequence, multi-parametric images, etc.)
- All node types: not just volumes but also transforms, models, markups, and any custom nodes
- Large data sets: up to 5000 bundles, with any number of nodes in each bundle, any size of nodes
Operations:
- Import from sequence metafile (time sequence of a 2D image and multiple tool tracking data)
- Save into scene file
- Load from scene file
- Browsing sequence items: automatic replay, prev/next item; ability to show multiple items at the same time
- Modification of sequence items: add/delete, change bundle name, parameter

Even after extensive MRML scene optimization, handling of large data sets (more 1000+ nodes) is not feasible due to the inefficiency of MRML widgets (node selector combo boxes, scene hierarchy trees; due to each widget maintaining its own qMRMLSceneModel)
Plan: store one node per sequence and store each item inside that sequence node (similarly to MultiVolume, but for any node type)
