Thread safe Parser?

[gingerwizard]

Can we assume the parser is thread safe and can be used by multiple threads concurrently for parse?

In simdjson, you should have a distinct parser instance per thread.

I've reopened this because at the python level, we can prevent people from shooting themselves in the foot and using a parser across threads. We can't stop someone whose using ctypes or or otherwise interacting from C land but it's better than nothing.
