updates proxy class usage

- ProxyClass class is inheriting from DeviceConnection and is only used for topmost proxy
- classes of nested proxy objects are dynamically created to keep their component types
- adds _initialise method to ProxyClassMixin as I cannot pass sio_client and loop to each
component_class (initialising a class with multiple base classes will pass the arguments passed to
the constructor to each initialiser function)
