### 1.1.0
Added support for generic arguments. Works like a generic Func, where the last generic argument is the return type of the function. Having only the return value will look for getter properties aswell. Having > 1 generic argument will only look for suitable public methods

Looks and acts like a UnityEvent.
Supports both GUI and UI Toolkit. Tested with Unity 2020.3, 2021.3, 2022.2, 2023.1.
Tested in standalone Windows and Android builds, both with Mono and IL2CPP.
Version 1.1 supports generic parameters.
If there are no generic parameters for the func, you'll also be able to assign getter properties.
