- Deleted `seed-manzana.go`, `site-holder-attach.go`, `types.go`, `utils.go`, `main.go` files from both `mssql-info-test` and `mssql-test` directories.
- Removed `pg-info-test/main.go` and `test-etl/main.go` files.
- Eliminated `wkb-to-ewkb/main.go` for unused WKB to EWKB conversion functionality.
- Cleaned up associated functions and types that are no longer needed.
