What changes were proposed in this PR?

Upgrade proj4sedona from 0.1.2 to 0.1.3 and add a regression test for transforming RT90 (EPSG:3021) to SWEREF99 TM (EPSG:3006).

Sedona 1.9 switched CRS transformation to proj4sedona, but version 0.1.2 lacked the generated RT90 datum definition. The transform therefore omitted the required datum shift and produced an error exceeding 180 metres. Version 0.1.3 includes the complete upstream datum registry and restores the RT90 Helmert transformation.
