Update shade support

[alexbrasetvik]

First, thanks for the great work, @jankrib :)

I have two different kinds of shades. Both types would react to the move_down operation, but not the two other operations, where I found the state constants sent to differ from those that the public app makes.

Some of my shades support setting a direct position, e.g. 50%, while some of the other shades do not. I think the logic for detecting this should be right, but hard to tell through reverse engineering and guessing :)

@jankrib Does the existing code move shades correctly for you? If so we'll need to detect differences in components/state somehow so my changes do not break things.

Here's the raw component data I get on an awning shade not supporting setting a direct position:

raw_component = {'compId': 8694179, 'compType': 86, 'name': 'Pergola - høyre', 'icon': 637, 'order': 72, 'versionFW': '7.1', 'info': [{'text': '1111', 'type': 2, 'icon': 1, 'value': '3'}, {'text': '1119', 'type': 2, 'icon': 1}]}
raw_state = {'deviceId': 10219, 'name': 'Pergola - høyre', 'icon': 633, 'order': 113, 'compId': 8694179, 'chId': 0, 'cat': 0, 'devType': 102, 'configured': True, 'shType': 3, 'shControl': 3, 'shRuntime': 60, 'shCounterRuntime': 5000, 'shStepDur': 300, 'shSafety': 0, 'shSafetyPos': 0, 'shCounterPause': 800, 'shHasSlats': False, 'shSlatRuntime': 300, 'shInvertOutput': False, 'curstate': 1, 'shPos': 100, 'shSlatPos': 255, 'shCalInfo': 0, 'cloudUsage': True, 'info': [{'text': '1109', 'type': 2, 'icon': 1, 'value': '30'}, {'text': '1132', 'type': 1, 'value': '100%'}]}

This one does support setting a position, e.g. 50% closed:

raw_component = {'compId': 8627654, 'compType': 86, 'name': 'Screen 4 - høyre vindu', 'icon': 637, 'order': 50, 'versionFW': '7.1', 'info': [{'text': '1111', 'type': 2, 'icon': 1, 'value': '2'}, {'text': '1119', 'type': 2, 'icon': 1}]}
raw_state = {'deviceId': 190, 'name': 'Screen 4 - høyre vindu', 'icon': 631, 'order': 71, 'compId': 8627654, 'chId': 0, 'cat': 0, 'devType': 102, 'configured': True, 'shType': 1, 'shControl': 2, 'shRuntime': 1, 'shCounterRuntime': 5000, 'shStepDur': 300, 'shSafety': 0, 'shSafetyPos': 0, 'shCounterPause': 800, 'shHasSlats': False, 'shSlatRuntime': 0, 'shInvertOutput': False, 'curstate': 1, 'shPos': 100, 'shSlatPos': 255, 'shCalInfo': 1, 'cloudUsage': True, 'info': [{'text': '1109', 'type': 2, 'icon': 1, 'value': '41'}, {'text': '1132', 'type': 1, 'value': '100%'}]}

I actually don't have a cover myself, so I was coding blind. Thank you for contributing. Let's get this in

Awesome. Thanks for the quick follow-up :)
