refactor!: Generalize tile traversal interface

[kylebarron]

Breaking changes

API change for low-level tileset traversal in deck.gl-raster, but no high level API changes.

Change list

• Create a new generalized interface for tile traversal. Currently called TilesetDescriptor (name subject to change)
• Change tile traversal to exclusively use this interface. So tile traversal is no longer tied to TileMatrixSet.
• Implement TileMatrixSetAdaptor for TilesetDescriptor, so there are no breaking changes in the high level API (only in the lower-level deck.gl-raster API)
• Add new Corners type to describe rotated bounding box
• Update sampling in sampleReferencePointsInEPSG3857 to use bilinear interpolation from the corners, not 1D interpolation from the axis-aligned bounding box.
  • Create bilerpPoint helper to clarify what this is doing
• Include claude plan for zarr integration

Precursor for Zarr support in #166, #178

Relevant for #375, #327
