I added some parameters to the packed_scene from path constructor

Asuming we're treating scene.hpp (well the project in general) as a public framework/library of sorts I thought having access to ResourceLoader parameters through the constructor would be quite convenient.

ResourceLoader has some parameters that are otherwise inaccessible.

Notably the CacheMode, which defaults to 1 = CACHE_MODE_REUSE. This caches previous loads and reuses them, which is pretty neat, but the use of this cache may not always be required, so it's best to give the user the option to change this mode.

yeah i think that makes sense. maybe one day it could be worth breaking out stuff like this into header only library that's easier to integrate into any codebase using gdextension. just something that could be used as common utilities for gdextension. i still need to work generic lambda / std::function<> / std::unique_ptr<> into the signals wrapper so any of those can be used as callbacks when a signal is emitted... or add the ability for hint flags to be passed into the property bindings code too (and really just confirm it can be used for all possible bindings).
