LimaCCDs simulator is not usable with amesh
By default the simulator preallocate the whole expected images.
A basic amesh(sx, 0,1,100,sy,0,1,100,0.0001, lima_simulator)
will allocate 101x101 images of shape 1024x1024
Which is about about 10GB for a very small scatter.
It would be good to find a work around.
