URL: https://github.com/apache/datafusion/issues/24396

   ### Is your feature request related to a problem or challenge?
   
   The `Map` type is supported in DataFusion/Arrow, but it's not possible to 
directly create tables with it. Example:
   ```sql
   > create table t (a map(int, int));
   This feature is not implemented: Unsupported SQL type Map(INT, INT)
   ```
   
   However this works:
   ```sql
   > create table t as select map {1: 2};
   0 row(s) fetched.
   ```
   
   ### Describe the solution you'd like
   
   Be able to create tables with the `Map` type.
   
   ### Describe alternatives you've considered
