Re: [I] [Python][Interchange protocol] Export boolean columns as bit-packed values [arrow]

   @AlenkaF I would support exporting booleans as bit-packed booleans. It is more in line with the protocol: zero copy if possible. It is up to the person implementing `from_dataframe` to handle reading bit-packed booleans. That is how I have implemented it in Polars.
   
   I now have a special case for pyarrow's 8-bit boolean type, but I'd like to get rid of it if at all possible, as it doesn't make much sense, in my opinion.
