rerun_py.dataframe: add support for .filter_index_values

[jleibs]

What

• Add a new type helper for IndexValues (in general some variation of this will be useful for other APIs)
• Added a dependency on numpy package for ArrayLike functionality
  • numpy has an old dep on ndarray.
  • This has already been fixed but not yet released: Support ndarray 0.16 PyO3/rust-numpy#439
• ChunkedArrays are sadly are more complicated (see the note in: https://docs.rs/arrow/latest/arrow/pyarrow/index.html)

IndexLike is a misleading name: this does not represent an index, it represents a series of index values. 🤔

Ahh, good call.
