   ## Did you read the Contributor Guide?
   
   - Yes, I have read the [Contributor 
Rules](https://sedona.apache.org/latest/community/rule/) and [Contributor 
Development Guide](https://sedona.apache.org/latest/community/develop/)
   
   ## Is this PR related to a ticket?
   
   - Yes, and the PR name follows the format `[GH-XXX] my subject`. Closes #3103
   
   ## What changes were proposed in this PR?
   
   Bumps the `proj4sedona` dependency **0.1.0 → 0.1.1** and re-enables the 5 
`CrsRoundTripComplianceTest` cases that were `@Ignore`'d against #3103.
   
   proj4sedona 0.1.1 fixes the CRS-serialization interop issues that made 
`RS_CRS` PROJ-string export non-idempotent for several projected CRSs:
   - WKT1 emits `TOWGS84` in human units (arc-seconds / ppm)
   - WKT / GeoTools method names are normalized to PROJ short codes on export 
(e.g. `Polar_Stereographic` → `stere`)
   - Canonical PROJ short codes are registry-owned
   - Polar Stereographic variant A/B selection is consistent across proj-string 
/ WKT1 / WKT2
   
   Re-enabled cases: `EPSG:5070` (Albers), `EPSG:28992` (Oblique 
Stereographic), `EPSG:27700` (OSGB TM), `EPSG:3577` (Australian Albers), 
`EPSG:3111` (Vicgrid LCC 2SP). Transforms were never affected — this was export 
idempotency only.
   
   ## How was this patch tested?
   
   Built the `common` module and the Spark CRS path against proj4sedona 0.1.1:
   - `common` full suite: **1145** tests, 0 failures / 0 errors / 0 skipped — 
including `CrsRoundTripComplianceTest` (**81**, all cases active, 0 skipped)
   - `CRSTransformProj4Test` (Spark `ST_Transform` → proj4sedona): **36**, 0 
failures
   - `CRSTransformationTest` (Spark core CRS): **1**, 0 failures
   
   ## Did this PR include necessary documentation updates?
   
   - No, this PR does not affect any public API so no need to change the 
documentation.
