[feat] Consider using msgpack5 for compression

[robertsLando]

https://github.com/mcollina/msgpack5

Option: compressMode: 'msgpack5' default to false

Then a compressed line in jsonl file will look like:

{"k":"1668612831392", "v": "0xaaaaaaa"}

Where aaaaaaa is the encoded object output from msgpack5 ecncode function.

To keep back compatibility we should allow to read uncompressed existing jsonl dbs, this means that when reading the db file and compression is enabled, when v is a string we should decode it with the compression choosed, otherwise read v as before
