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

* compress sstable with zstd
* add some details to sstable readme
* compress only block which benefit from it
* multiple changes to sstable
make compression optional
use OwnedBytes instead of impl Read in sstable, required for next point
use zstd bulk api, which is much faster on small records
* cleanup and use bulk api for compression
* use dedicated byte for compression
* switch block len and compression flag
* change default zstd level in sstable
* Added proptest on columnar merge with a shuffle
Made column serialization more explicit.
Bugfix when a bytes column is missing, and with a shuffle.
Improved the cardinality detection logic / column detection.
* Code review
* CR comments

* Faster range queries
This PR does several changes
- ip compact space now uses u32
- the bitunpacker now gets a get_batch function
- we push down range filtering, removing GCD / shift in the bitpacking
codec.
- we rely on AVX2 routine to do the filtering.

* document a new sstable format
* add support for changing target block size
* use new format for sstable index
* handle sstable version errror
* use very small blocks for proptests
* add a footer structure
* 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.

dynamic dispatch seems to be really expensive, move the buffer in front of the dynamic dispatch, to reduce the number of calls into the dynamic dispatched collector.
* Adding a write schema to columnar's merge operations.
* Added unit test checking min/max when columns are empty.
* CR comment
* Rename to value_type_to_column_type
`ColumnValues` wrongly located in column_values/column.rs due to
historical reason moves to column_values/mod.rs
u128 stuff gets its own directory like u64 stuff.
The new fast field code, based on columnar, had a larger minimum memory
footprint, causing the first docuemnt to trigger a flush of the asegment
in this unit test.
This PR prevents the allocation of a large capacity for the different hashmap tables
using in the columnar writer.
Closes#1859
* Removed the sorting logic that forced column type to be sorted like
ColumnTypes.
* add comments
