[I] rust/sedona-functions: Add `ST_xxxFromWKB()` functions [sedona-db]

["paleolimbot (via GitHub)" <gi...@apache.org>]

paleolimbot opened a new issue, #206:
URL: https://github.com/apache/sedona-db/issues/206

   As part of #174, there are a few functions that are the same as WKB + validation:
   
   - ST_LinestringFromWKB (with alias: ST_LineFromWKB)
   - ST_PointFromWKB
   
   These are slightly different than our existing "FromWKB/Binary" because our existing fromwkb/binary is lazy and doesn't copy anything. We do have a validation loop and we can add an optional type validator:
   
   https://github.com/apache/sedona-db/blob/95c156d507f9ce67dde1fd3ec6e1a196c70a39a6/rust/sedona-functions/src/st_geomfromwkb.rs#L111
   
   ...could be
   
   ```rust
   if let Some(expected_geometry_type_id)  = self.expected_geometry_type {
     // Create a builder
     executor.execute_wkb_void(|_maybe_item| {
       // add them item or add null to the builder for _maybe_items whose type id doesn't match
     })?;
     executor.finish(builder.finish())
   } else {
     executor.execute_wkb_void(|_maybe_item| Ok(()))?;
     args[0].cast_to(self.out_type.storage_type(), None)
   }
   ```
   
   The steps for adding a parameter to the Udf struct and creating the udf with documentation are very similar to https://github.com/apache/sedona-db/issues/205
