Improve error handling for tweetfinder timeout

Enhanced the tweetfinder error handling by introducing a unique error `ErrTimeoutSelectFinder` used for instances of tweetfinder timeouts. Modified corresponding sections in `pool.go` and `watcher.go` to throw and process this new error, respectively. This ensures timeouts are treated as unique error cases, promoting better error identification and management.
