Feature request : user friendly methods for Querybuilder , show and sql

[djouallah]

first thanks for finally exposing the SQL interface of datafusion inside delta_rs, it just make perfect sense, it was always hard to explain why we need to download datafusion twice.

this is just for aesthetic reasons and for compatibility with the broader ecosystem

QueryBuilder().execute, it will be nice to have QueryBuilder().sql()

and instead of writing
print(pa.Table.from_batches(QueryBuilder().execute(value)))

something like this will be nice

QueryBuilder().sql("select 42").show()

thank you again,

@djouallah can you make a PR for this?

@ion-elgreco I wish, I barely knows how to write simple Python and a bit of sql :(
