Read shutter position from OWN status message

[feodor85]

I have Legrand 067263 shutter.

In the documentation for the equipment there is a section:

If your shutter has traditional limit switches, place the shutter in the fully open position and press the button indicated, holding for more than four seconds. The shutter closes fully, opens fully, and then settles in an intermediate position. Do not interfere with the unit during this phase. The unit has memorized the shutter opening and closing times. Next, memorise the desired position (preset).

After config the device sends position status messages:

• after full opening sends: *2*0*770677101#9##*#2*770677101#9*10*10*100*000*0##
  where 100 is position;
• after middle opening sends *2*0*770677101#9##*#2*770677101#9*10*10*45*000*0##
  where 45 is position

Currently the binding ignores these messages:

It would be more precise to read the shutter position from status messages.
