[gree] the Gree binding should allow for setting the swingUpDown setting to values 7-11

[taboneclayton]

As per documentation on the gree-remote project, Gree AC devices should support modes 7, 8, 9, 10, 11 for the SwUpDn field. These values map to partial swings as defined below:

7: swing in the downmost region (5/5)
8: swing in the middle-low region (4/5)
9: swing in the middle region (3/5)
10: swing in the middle-up region (2/5)
11: swing in the upmost region (1/5)

In the Gree openHAB binding this is mapped to the swingUpDown channel. The method GreeAirDevice#setDeviceSwingUpDown includes a comment specifying that values between 0 and 11 should be allowed. However the validation code only allows values between 0 and 6.

This is quite an easy fix and I could apply the fix myself by wanted to open an issue first to make sure that this would be a wanted fix/improvement.

@fwolter, @markus7017 would you like me to implement a fix for this issue?

[markus7017]

sure, one thing is the validation, but the values are also mapped to textual channel values, please check both aspects

I already noticed this, bit nobody reported this issue and if I remember correctly it was the same way in the code I took over
