[client-v2] Handling errors from a server

[chernser]

When compression is on (default case) and error happens - it is read from a raw stream, but should be wrapped with LZ4 Input Stream.

Steps to reproduce

1. send query select asd123
2. observe error with non-ascii symbols

Expected behavior

Error message should be a human readable string

Code example

Error log

• CREATE TABLE statements for tables involved:
• Sample data for all these tables, use clickhouse-obfuscator if necessary

Didn't you already fixed this issue in #1830 ? Your description seems reproducible before this PR, and not after it.

Good day, @Am-phi!
yes, #1830 fixes most of the problems and I left issue open to test more and fix may be edge cases.
There is a tricky case when error is within data stream in the format of the data stream. It is fixed too, but I would spend sometime for additional tests.
