[Documentation needed] Goroutine/thread-safety

[mivanovcpd]

Feature description: There's no documentation on whether you need to create multiple protovalidate instances if you want to call them in parallel from goroutines.

Problem it solves or use case: Prevent race conditions.

Proposed implementation or solution: Proper documentation on the best practice.

Contribution: As a non-dev on the project, I can't contribute much since I don't know if it was designed to be thread-safe or not.

Examples or references: For the JVM version, there was an explicit mention to create multiple instances since it's not thread-safe.

Additional context:

I just read the code itself, it said it supports validation in parallel. Closing.
