[FEAT] Add option for exporting zap types into separate file.

[passhley]

Describe your feature

Currently types you write inside your zap file get exported in both the server and client files, this is usually fine. However, I'm pretty nitpicky about separation, and I am not a fan of having my shared files access client files just to access types.

Implementation Details

opt types_output = "src/shared/types/zap.types.luau
This would create a new file in the location specified, and then your server & client would gather the types necessary from there.
