Somfy Shades - "My" button should toggle state of shades.

[waffledork]

Is your feature request related to a problem? Please describe.
When the "My" command is used, the shade still maintains its current state, whether that's "Open" or "Closed". The reason that people set up a My Position is because they want to limit how far their shade closes and/or opens.

For example, we have shades that could go all the way to the floor (if we close them) but we set up a My Position to stop them at knee-level because we have frosted glass at the bottom anyway and it prevents our cats from playing with the shades. However, we still consider the shades to be "Closed" in these instances.

Describe the solution you'd like
When the "My" button is pressed, I would like the shade to toggle. If it was "Open", it should now be "Closed". If it was "Closed" when the "My" button is pressed, the state should now read "Open".

This will provide Somfy shade owners with more flexibility in defining what constitutes as "Open" and "Closed".

Describe alternatives you've considered
I use Home Assistant (Bond Bridge works fantastically with it!) and I have a toggle that keeps track of whether my shade is open or closed. I have an automation set up to toggle that toggle when the "My" button is used. While this is a viable workaround, I think it makes sense to have Bond Bridge toggle the shade's state when the "My" button is pressed.
