Query should not support only str

[pkit]

Currently query data is expected to be a str instance.
Which limits how I can use it.
For example, embedding binary data (while supported by ClickHouse) is not possible.
Maybe exposing some bytes-based raw_query(something) interface is a good idea?
Right now I need to subclass or monkey-patch it in...

Just an example of what works in raw ClickHouse HTTP:

SELECT * FROM format(Parquet, $<random uuid>$<Parquet binary data>$<random uuid>$) FORMAT CSV

Nice!
