Class based resource collection

[cmgriffin]

Added a static typed version of the object created by connect_resources() with similar helper functions for acting on groups of devices.

Usage options:

• Class Variables:

class MyResourceCollection(ResourceCollectionBase):
    device1 = Resource1(x,y,z)
    device2 = Resource2(x,y,z)

env = MyResourceCollection()

• Type Hints with a json file:

class MyResourceCollection(ResourceCollectionBase):
    device1: Resource1
    device2: Resource2

env = MyResourceCollection(
    {
        "device1":{"address":"12345"},
        "device2":{"address":"67890"},
    }
)

• Instance Variables:

class MyResourceCollection(ResourceCollectionBase):
    def user_init(self):
        self.device1 = Resource1(x,y,z)
        self.device2 = Resource2(x,y,z)

env = MyResourceCollection()
