Merge #190

190: Add `get_raw_index` method r=curquiza a=ginglis13

### Description

Add get_raw_index to return `JsonIndex` object. Refactor `get_index` to first use `get_raw_index` before calling `into_index` on resulting `JsonIndex` object.

Addresses #188 


### Testing

Added doc test for new `get_raw_index` method and ran tests against meilisearch instance via `cargo test -- --test-threads=1`
