   I noticed that there is currently no support yet in the `from_dataframe` 
function for boolean columns with bitsize 1. Is there an issue for implementing 
this?
   
   ```python
   import polars as pl
   import pyarrow as pa
   import pyarrow.interchange
   
   df = pl.Series("a", [True, False], dtype=pl.Boolean).to_frame()
   dfi = df.__dataframe__()
   pa.interchange.from_dataframe(dfi)
   # NotImplementedError: Conversion for (<DtypeKind.BOOL: 20>, 1, 'b', '=') is 
not yet supported.
   ```
