Shadows dissapear after some distance

See bevyengine/bevy#5789
Looks like we have to move the projection with the player / the camera (careful, don't inherit the camera's rotation!) or switch to a point light for the sunlight. Using multiple directional lights / one per object stacks the light and causes weirdness, don't try that.

Looks like a native solution is on its way: bevyengine/bevy#7064
Update: merged, waiting for Bevy v0.10
Looking forward to the builder (bevyengine/bevy#7456)!

Update: now only blocked by #159

Yes! Cascaded shadow maps should avoid the need to keep moving the shadow projection. You may still want to customize the maximum shadow distance, but that's relative to the viewing camera now, instead of some absolute volume.
