rebuild JSON : LZ4 compressed

ASTER::ACTION::JSON::Reconstruct from MessagePack data compressed w/ LZ4 & enc. in Base64.

Parse Base64-encoded MessagePack and load it into nlohmann/json.

This function reconstructs JSON from data serialized with ASTER. For developers, we have published a Python implementation of the data restoration method.

By reproducing the published steps, serialization can be performed in other environments. That can then be reconstructed into JSON (the author has not tested this).

JSON is a text-based data format, but MessagePack is a format that allows handling it in binary form.

The conversion to MessagePack uses nlohmann/json’s to_msgpack.
