* Refactoring of the score tweaker into `SortKeyComputer`s to unlock two features.
- Allow lazy evaluation of score. As soon as we identified that a doc won't
reach the topK threshold, we can stop the evaluation.
- Allow for a different segment level score, segment level score and their conversion.
This PR breaks public API, but fixing code is straightforward.
* Bumping tantivy version

* Optimization when posting list are saturated.
If a posting list doc freq is the segment reader's
max_doc, and if scoring does not matter, we can replace it
by a AllScorer.
In turn, in a boolean query, we can dismiss all scorers and
empty scorers, to accelerate the request.

Applied this command to the code, making it a bit shorter and slightly
more readable.

* Term are now typed.
This change is backward compatible:
While the Term has a byte representation that is modified, a Term itself
is a transient object that is not serialized as is in the index.
Its .field() and .value_bytes() on the other hand are unchanged.
This change offers better Debug information for terms.
While not necessary it also will help in the support for JSON types.
* Renamed Hierarchical Facet -> Facet
go_to_first_doc was typically calling seek with a target smaller than
doc.
Since SegmentPostings typically do a linear search on the full block,
regardless of the current position, it could have our segment postings
go backward.
- Change in the DocSet and Scorer API. (@fulmicoton).
A freshly created DocSet point directly to their first doc. A sentinel value called TERMINATED marks the end of a DocSet.
`.advance()` returns the new DocId. `Scorer::skip(target)` has been replaced by `Scorer::seek(target)` and returns the resulting DocId.
As a result, iterating through DocSet now looks as follows
```rust
let mut doc = docset.doc();
while doc != TERMINATED {
// ...
doc = docset.advance();
}
```
The change made it possible to greatly simplify a lot of the docset's code.
- Misc internal optimization and introduction of the `Scorer::for_each_pruning` function. (@fulmicoton)

Closes#547
* Clippy comments
Clippy complaints that about the cast of &[u32] to a *const __m128i,
because of the lack of alignment constraints.
This commit passes the OutputBuffer object (which enforces proper
alignment) instead of `&[u32]`.
* Clippy. Block alignment

* Added comment. Code simplification
* Removed the extraneous freq block len hack.

* Make TopCollector generic
Make TopCollector take a generic type instead of only being tied to
score. This will allow for sharing code between a TopCollector that
sorts results by Score and a TopCollector that sorts documents by a fast
field. This commit makes no functional changes to TopCollector.
* Add TopFieldCollector and TopScoreCollector
Create two new collectors that use the refactored TopCollector.
TopFieldCollector has the same functionality that TopCollector
originally had. TopFieldCollector allows for sorting results by a given
fast field. Closestantivy-search/tantivy#388
* Make TopCollector private
Make TopCollector package private and export TopFieldCollector as
TopCollector to maintain backwards compatibility. Mark TopCollector
as deprecated to encourage use of the non-aliased TopFieldCollector.
Remove Collector implementation for TopCollector since it is not longer
used.
