[FEATURE]-Add support for HD-MDNxM-4KZ-E devices

[jkdevito]

HD-MDNxM-4KZ-E devices have a different base class from the 4K-E devices. Add support for 4KZ-E switchers (4x1, 4x2, 8x8)

[jkdevito]

Support has been added for 4KZ-E devices, refactored 4K-E support, removing the obsolete classes and renaming the 4kebridgeableController to 4kcontroller.

Features are pending testing with hardware to validate additions.
