Support for 4D+t data

Hi there,

A t_axis option in cellpose.models.Cellpose.eval would be awesome.

on the to-do list! would you want to have stitching as an option for the t_axis or just support for fast processing along the t_axis? (I have now updated so that the z_axis is batched on the GPU even without stitching to increase run-speed)

assuming stitching means "tracking" in this context, I'd expect that when I see "3/4D+t" is supported! and great to hear this is on the list : )
