Update ares_query_txt_result_chunk to return bytes rather than str

[maelp]

The RFC1035 specification says that TXT records are allowed to contain data made of arbitrary binary data, but right now aiodns is parsing it as a str, and therefore will stop on a null byte, this PR fixes this

I think we need to apply the same to ares_query_txt_result, don't we? Also, I wonder why the GH action with the tests didn't run...

I’m on holidays for a few days but I can do it when I come back

Sure thing, no rush, and thanks for helping out with this!

@saghul I guess that now that both return bytes it should work as expected

It seems that the test_query_txt_multiple_chunked_with_non_ascii_content test fails because it is checking the server txt-non-ascii.dns-test.hmnid.ru which does not respond

Also the test_idna_encoding_query_a test seems to fail because the A query to españa.icom.museum seems to respond with a NXDOMAIN and SOA response (non-existent domain)
