What

Certain arrow implementations required that dictionary keys be signed.

Also the type returned by static data columns was missing the arraylist.

Out of curiosity, where did you encounter that?

Update the dataframe view to use re_dataframe and egui_table (#7380)
e9b02e3 
### What

- Closes #7279

Major update to the dataframe view
- display the data return by the new `re_dataframe` crate
  - the PoV entity/component is now actually used
  - entities are now always columns
    - see #7379 
- use [`egui_table`](https://github.com/rerun-io/egui_table) for the
table
  - hierarchical header
  - sticky columns
  - and much more...

TODO:
- [x] fix after merging #7383

Certain arrow implementations required that dictionary keys be signed.

Out of curiosity, where did you encounter that?

See for example the official c++ API: https://arrow.apache.org/docs/cpp/api/datatype.html#_CPPv410dictionaryRKNSt10shared_ptrI8DataTypeEERKNSt10shared_ptrI8DataTypeEEb

I also hit this when trying to convert a dictionary to pandas:

pyarrow.lib.ArrowTypeError: Converting unsigned dictionary indices to pandas not yet supported, index type: uint32

In general Arrow frequently falls back to usage of signed-integers in key design places in support of least-common-denominator approach to languages that don't handled unsigned values well

The spec for arrays

Array lengths are represented in the Arrow metadata as a 64-bit signed integer.

The spec for lists

The offsets are the same as in the variable-size binary case, and both 32-bit and 64-bit signed integer offsets are supported options for the offsets.

The spec for dictionary suggests:

Since unsigned integers can be more difficult to work with in some cases (e.g. in the JVM), we recommend preferring signed integers over unsigned integers for representing dictionary indices. Additionally, we recommend avoiding using 64-bit unsigned integer indices unless they are required by an application.
