Picam v0.2.0 Picam.FakeCamera

A fake version of Picam.Camera that can be used in test and development when a real Raspberry Pi Camera isn’t available.

All the normal configuration commands are accepted and silently ignored, except that:

size can be set to one of 1920x1080, 1280x720, or 640x480. This will result in a static image of that size being displayed on each frame.
fps can be set, which will result in the static images being displayed at roughtly the requested rate.

In addition, a custom image can be set using set_image/1, which is be displayed on each frame until a new image is set or the size is changed.
