sn:// schema interopability

[dimzon]

Description suggestions

Current sn:// link format use binary JVM serialization with variable-length int encoding. It's really hard to parse or build such links in 3-rd party tools/scripts in python on php or bash.

Necessity of recommendations

I suggest to add new schema (let's name it sn2) - based on well-known formats - something like vmess: base64-url-safe + json
