Linear GDO Support

[dewbot6]

Hello,
I am able to control my Linear garage door with dry contact support, but I was curious if their protocol could be read to control the light and get door position readings (similar to security + 1/2).

I saw this issue: #145 and have tested 1.0 and 2.0, but neither seems to work. Linear does sell a new wall panel that can turn the light on and lock: https://linear-solutions.com/product/nice-g-o-wallstation/
