feat(client): add configurable timeout support for all API operations

- Add configurable timeouts for single, batch, and list API operations
- Default timeouts: 5s (single), 30min (batch), 60s (list API)
- Users can override defaults via GeocodioClient constructor
- Pass appropriate timeout from each method to _request()
