Miraculously, I was able to get this working mere minutes before my talk at Data Science Summit. Let me know any comments on the general approach.

The general approach looks good, +1.

Thanks -- I'll get the build passing and merge. I am not able to read very many flat Parquet files right now (for example: Impala's Parquet files do not have the UTF8 annotation for strings, similarly timestamps are stored in Int96), so will create a bunch of JIRAs to track these.

In the absence of a separate metadata (like the Hive metastore), we'll have to make some default guesses about the actual schema and eventually provide some options to set the column logical types explicitly when there is ambiguity.

ARROW-16568: [Java] Enable skip BOUNDS_CHECKING with setBytes and get…
b0db6d8 
…Bytes of ArrowBuf (apache#104)

We have BOUNDS_CHECKING_SKIP in ArrowBuf.setByte or ArrowBuf.getByte, it helps to remove unexpected bounds checks. However, it doesn't exists in ArrowBuf.setBytes or ArrowBuf.getBytes, which makes 10% cpu time cost for checking bounds in our environment.

Closes apache#13161 from jackylee-ch/skip_bounds_check_for_set_or_get_bytes

Covers all of `pc.(and_ | and_kleene | and_not | and_not_kleene | or_ | or_kleene | xor)`

Also being more consistent with `ArrayOrChunkedArray[Any]` everywhere

* chore: Ignore `fsspec` `[import-untyped]` (apache#210)

```py
_fs.pyi:18: error: Skipping analyzing "fsspec": module is installed, but missing library stubs or py.typed marker  [import-untyped]

* feat: Convert `types.is_*` into `TypeIs` guards (apache#215)

* chore: Add `types.__all__`

* feat: Convert `types._is_*` into `TypeIs` guards

I've been using this for a little while, but makes more sense to live in the stubs
https://github.com/narwhals-dev/narwhals/blob/16427440e6d74939c403083b52ce3fb0af7d63c7/narwhals/_arrow/utils.py#L44-L67

* fix: Resolve `bit_wise_and` overlaps (apache#214)

Fixes 3 errors:
```py
compute.pyi:608:5 - error: Overload 1 for "bit_wise_and" overlaps overload 4 and returns an incompatible type (reportOverlappingOverload) compute.pyi:608:5 - error: Overload 1 for "bit_wise_and" overlaps overload 5 and returns an incompatible type (reportOverlappingOverload) compute.pyi:620:5 - error: Overload 3 for "bit_wise_and" will never be used because its parameters overlap overload 1 (reportOverlappingOverload)
```

* fix: Resolve `list_*` overlapping overloads (apache#213)

* fix: Resolve `list_value_length` overlaps

* fix: Resolve `list_element` overlaps

* fix: Resolve `list_(flatten|slice|parent_indices)` overlaps

An improvement, but still not that accurate

* fix: Include `VarianceOptions` in `TableGroupBy.aggregate` (apache#212)

- Follow-up to apache#197
- Noticed while writing up (narwhals-dev/narwhals#2385)
  - We already use it for `std`, `var` in https://github.com/narwhals-dev/narwhals/blob/16427440e6d74939c403083b52ce3fb0af7d63c7/narwhals/_arrow/group_by.py#L81-L82

* fix: Resolve `Scalar.as_py` warnings for `DictionaryType` (apache#207)

> scalar.pyi:75:20 - warning: TypeVar "_AsPyTypeK" appears only once in generic function signature
>     Use "object" instead (reportInvalidTypeVarUse)
> scalar.pyi:85:20 - warning: TypeVar "_AsPyTypeK" appears only once in generic function signature
>     Use "object" instead (reportInvalidTypeVarUse)

Instead just using `int`, which should be all that is possible from:

* fix: Add default to `pc.sort_indices` (apache#216)

* fix: Add default to `pc.sort_indices`

Fixes narwhals-dev/narwhals#2390 (comment)

Default is specified in https://arrow.apache.org/docs/python/generated/pyarrow.compute.sort_indices.html

* refactor: Reuse some aliases

* fix: Allow `list_size` with `Field` in `pa.list_` (apache#218)
