* store DateTime as nanoseconds in doc store
The doc store DateTime was truncated to microseconds previously. This
removes this truncation, while still keeping backwards compatibility.
This is done by adding the trait `ConfigurableBinarySerializable`, which
works like `BinarySerializable`, but with a config that allows de/serialize
as different date time precision currently.
bump version format to 7.
add compat test to check the date time truncation.

* Fix trait bound of StoreReader::iter
Similar to `StoreReader::get`, `StoreReader::iter` should only require
`DocumentDeserialize` and not `Document`.

The dependency requires users to implement an API they may not use.

more readable.

* add memory limit for aggregations
introduce AggregationLimits to set memory consumption limit and bucket limits
memory limit is checked during aggregation, bucket limit is checked before returning the aggregation request.
* Apply suggestions from code review

In addition, it isolates the doc compressor logic,
better reports io::Result.
In the case of the same-thread doc compressor,
the blocks are also not copied.
* Added sstable and enabling it by default, and parallel boolean query.
* Added async API for FileSlice.
* Added async get_doc
* Reduce blocksize to 32_000
* Added debug logs
Quickwit specific feature a hidden behind the quickwit feature flag.
Change Footer version handling, Make compression dynamic
Change Footer version handling
Simplify version handling by switching to JSON instead of binary serialization.
fixes#1058
Make compression dynamic
Instead of choosing the compression during compile time via a feature flag, you can now have multiple compression algorithms enabled and decide during runtime which one to choose via IndexSettings. Changing the compression algorithm on an index is also supported. The information which algorithm was used in the doc store is stored in the DocStoreFooter. The default is the lz4 block format.
fixes#904
Handle merging of different compressors
Fix feature flag names
Add doc store test for all compressors
* add iterator over documents in docstore
When profiling, I saw that around 8% of the time in a merge was spent in look-ups into the skip index. Since the documents in the merge case are read continuously, we can replace the random access with an iterator over the documents.
Merge Time on Sorted Index Before/After:
24s / 19s
Merge Time on Unsorted Index Before/After:
15s / 13,5s
So we can expect 10-20% faster merges.
This iterator is also important if we add sorting based on a field in the documents.
