allow subfield access

[bmschmidt]

This makes it possible for deepscatter to access not just single-depth fields, but also structs that can get probed into.

Struct<x: Float32, y: Float32>

This is useful because often a single transformation should create two or more columns.

---

Important

Enhance Deepscatter to support subfield access in struct columns, enabling complex data transformations and rendering.

• Behavior:
  • Allow access to subfields in struct columns, enabling transformations to create multiple columns.
  • Update get_column in Tile to handle subfields.
• Aesthetics:
  • Add subfield handling in Aesthetic and StatefulAesthetic classes.
  • Update columnKeys to include subfields.
• Rendering:
  • Modify ReglRenderer to support subfield access in buffer management.
  • Update neededFieldsToPlot to handle subfields.
• Data Management:
  • Enhance Deeptable to support subfield transformations.
  • Update apply_transformation in Tile to handle subfields.
• Utility:
  • Introduce TupleMap and TupleSet for managing nested keys.

The logic for setting the subfield property is repeated in multiple places. Consider extracting this logic into a separate function to adhere to the DRY principle. This issue is also present in other files where similar logic is used.

The get_column method is doing more than one thing: fetching the column and applying transformations if needed. Consider separating these responsibilities into distinct methods to adhere to the Single Responsibility Principle.
