Dario Mirovic 8e994b3890 test/cqlpy: add protocol exception tests ...

Add protocol exception tests that check errors and exceptions.

`test_process_startup_invalid_string_map`: `STARTUP` (0x01) with declared
map count, but missing entries - `read_string_map` out-of-range.

`test_process_query_internal_malformed_query`: `QUERY` (0x07) long string
declared larger than available bytes - `read_long_string_view`.

`test_process_query_internal_fail_read_options`: `QUERY` (0x07) with
`PAGE_SIZE` flag, but truncated page_size - `read_options` path.

`test_process_prepare_malformed_query`: `PREPARE` (0x09) long string declared
larger than available bytes - `read_long_string_view` in prepare.

`test_process_execute_internal_malformed_cache_key`: `EXECUTE` (0x0A) cache key
short bytes declared larger than provided bytes - `read_short_bytes`.

`test_process_register_malformed_string_list`: `REGISTER` (0x0B) string list
with truncated element - `read_string_list`/`read_string`.

Each test asserts an `ERROR` frame is returned and `protocol_error` metrics
increase, without causing C++ exceptions.
