Bug fixes

• Fixed bug in raw strings (thanks @benatkin 944).
• get_fn_metadata_list function is marked volatile.
• no-std plus sync should now build correctly (thanks stargazing-dino 947).

New Features

• It is possible to create a function pointer (FnPtr) which binds to a native Rust function or closure via FnPtr::from_dn and FnPtr::from_dyn_fn. When called in script, the embedded function will be called (thanks @makspll 952).

Enhancements

• The methods call_fn, call_native_fn, call_fn_raw and call_native_fn_raw are added to EvalContext (thanks @rawhuul 954).
• A new internals function, Engine::collect_fn_metadata, is added to collect all functions metadata. This is to facilitate better error reporting for missing functions (thanks therealprof 945).
