Add ZSTD compression (#430)

Browse source 
* Add support for zstd and split compression

Add support for using zstd as an alternative to native, lz4.

Upgrade lz4 to v1.9.4 (with ARM enhancements).

Allow for split compression algorithms - i.e. use native on journal, but lz4 on ledger.

* Switch to AdRoll zstd

Development appears to be active and ongoing.  No issues running on different linux flavours.

* Use realistic bucket name

* Update README.md

* Switch branch

* Add comment following review
