Add ST_SetCrs

[jesspav]

Summary

Currently, ST_SetSRID is out of line with other databases as it expects and accepts a string to allow for CRS codes and proj json. This change splits it into ST_SetSrid (which complies with standard expectations for that function) and the new ST_SetCRS which allows our users to provide more interesting and complex CRS definitions.

Issue: #29

Testing

Added unit tests, updated integration tests and ran tests with cargo run. benchmark tests will be provided in another PR.

Example

Examples correctly identifying setting the CRS:

> select ST_SRID(ST_SetSrid(ST_GeomFromText('POINT (1 1)'), 4837)) as srid;
┌────────┐
│  srid  │
│ uint32 │
╞════════╡
│   4837 │
└────────┘

> select st_srid(ST_SetCrs(ST_GeomFromText('POINT (1 1)'), 'EPSG:4837')) as geo;
┌────────┐
│   geo  │
│ uint32 │
╞════════╡
│   4837 │
└────────┘

Examples not accepting the other's arguments:

> select ST_SetSrid(ST_GeomFromText('POINT (1 1)'), 'EPSG:4837') as geo;
This feature is not implemented: st_setsrid([Wkb(Planar, None), Arrow(Utf8)]): No kernel matching arguments

> select ST_SetCrs(ST_GeomFromText('POINT (1 1)'), 4837) as geo;
This feature is not implemented: st_setcrs([Wkb(Planar, None), Arrow(Int64)]): No kernel matching arguments

Pull Request Overview

This PR splits the existing ST_SetSRID function to better align with database standards by creating two separate functions: ST_SetSRID which now accepts only integer SRID codes, and a new ST_SetCRS function which accepts string-based CRS definitions including EPSG codes and proj JSON.

• Refactored ST_SetSRID to accept only numeric SRID inputs for standards compliance
• Added new ST_SetCRS function that accepts string-based CRS identifiers
• Extracted common logic into a shared determine_return_type function

File	Description
rust/sedona-functions/src/st_setsrid.rs	Implements the function split with new ST_SetCRS struct, refactored validation logic, and comprehensive test coverage
rust/sedona-functions/src/register.rs	Registers the new st_set_crs_udf function in the function set and exports it in the stubs module
