Add additional device kinds for new products

[jsetton]

Related to #135, I added additional device kinds for new products based on the latest Ring App APK. This also includes adding the new knock detection capability check for the Peephole Cam.

Although, this should covers all the recent Ring product changes. From parsing the APK, it seems that the new Stick Up Cam is using the same device kind cocoa_camera for the battery and wire-in models. At this point, I am not sure how the app is able to differentiate them.

Moreover, there is a device kind called doorbell_scallop which could be the latest generation Doorbell 2 product but it's hard to tell. One thing for sure is that it is a battery operated product. Therefore, I omitted this device kind for the time being.

Finally, the 2nd generation of the Stick Up Cam Elite is identified as stickup_cam_elite_v2 in the app but it is still linked to device kind stickup_cam_elite. So another open question on how it can be differentiated from the previous generation (Elite vs Wired) which I believe doesn't have POE built-in.
