feat: add an API to time out query executions

Browse source 
Currently, if a predicate is hard to match on the Rust side, a sizable
query against a very large file can take forever, and ends up hanging.
This commit adds an API function `ts_query_cursor_set_timeout_micros` to
limit how long query execution is allowed to take, thereby negating the
chance of a hang to occur.
