Package spams too many logs without a way to hide them

**Is your feature request related to a problem? Please describe 🙏**
I'm also using the `logging` package in my app, which this package is using as well.

The package adds many logs that are getting annoying when working on unrelated features. Especially the `_log.fine('received response: $response');` in `algolia_hits_search_service.dart` prints the whole response object, which really spams the debug output. Took me quite a while to locate this as well.

**Describe the solution you'd like 🤔**
Make the logs optional or remove them entirely

Start with algolia_hits_search_service.dart and inspect the _log.fine call that prints the complete response. Determine how logging is currently exposed, then make the requested logging behavior optional or remove the noisy output; done means unrelated app debug output no longer receives these excessive logs.
