Deduplicate npm packages

[aljazerzen]

Ideally, we would not have 3 npm packages but a single one.

I did a little research, and currently it is possible, but not easy.

This is very similar issue: spruceid/didkit#208

One way to do it would mean creating two builds and merge results together, described here and here.

Another (easier) way would be to wait for this to merge: rustwasm/wasm-pack#313 rustwasm/wasm-pack#469
