This has ended up being a quite large project. Getting closer to something workable though, will try to get there this week

Getting closer here. @xhochy I won't do it in this PR, but I'd sort of like to consolidate all the array classes into array.h and the builder classes into builder.h, then remove the arrow/types subdirectory, if you have opinions

What's our policy on - vs _ in filenames`?

I'm not sure there's a hard and fast rule. Kudu seems to use dashes for internal files (and for unit tests), and _ as a separator in "public" headers:

https://github.com/apache/kudu/tree/master/src/kudu/client

so you would have

widget_xyz-test.cc

or

widget_xyz.h
widget_xyz-internal.h

https://google.github.io/styleguide/cppguide.html#File_Names

let me know what you think

The Kudu conventions seem fine to me. As long as we have some kind of convention I'm happy with it.

Okay. By this reasoning we should rename bit-util.h and memory-pool.h to bit_util.h and memory_pool.h. Can do this here or in another patch

OK, I'm done with this patch for now (before it gets any bigger) with a round trip JSON record batch test -- additional features / testing can get done in the course of building the integration test harness

For the sake of documentation and understanding, it would be nice to have a test that will read a JSON from a string embedded in the code here. Not sure how large the minimal possible version could be but that would be really helpful to understand the format.

PARQUET-797: Updates for ARROW-418 header API changes
912d7af 
I also changed this code to use `arrow/api.h` in some places to be less sensitive to some kinds of header changes.

Author: Wes McKinney <wes.mckinney@twosigma.com>

Closes apache#202 from wesm/PARQUET-797 and squashes the following commits:

d909443 [Wes McKinney] Fix arrow/util/status.h use
72758ea [Wes McKinney] Update arrow hash
4802052 [Wes McKinney] Update parquet/arrow to use arrow/api.h where relevant, ARROW-418 API changes

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:

Following up on what I thought was a simple stub issue, but we're both *too strict* and *too permissive* in different ways
