[PR] Feat/ffi scalar udf [datafusion-python]
timsaucer opened a new pull request, #1033:
URL: https://github.com/apache/datafusion-python/pull/1033
# Which issue does this PR close?
This addresses part of #1017 - the scalar UDFs
# Rationale for this change
This change enables users who have written DataFusion scalar UDFs to reuse them in `datafusion-python` with minimal overhead. They simply need to create a python object that exposes a PyCapsule that is the `FFI_ScalarUDF`.
# What changes are included in this PR?
Adds a function in ScalarUDF to create from a FFI object.
Add a full example and integration test.
# Are there any user-facing changes?
Existing interfaces are not changed, but additional `ffi_udf` function is added.

Putting into draft because we need the upstream DataFusion repository to release version 46 before this can be enabled.
