Collect and unify color overlays

[talonchandler]

Paired with https://github.com/czbiohub-sf/shrimPy/pull/141, which will close without merging.

This PR merges @edyoshikun's color overlays from shrimpy into recOrder while making necessary changes to both sets of functions:

• accept czyx-shaped arrays as a single input for compatibility with our parallelization strategy. This required a fairly significant change to recOrder's handling of dask arrays.
• return (3, Z, Y, X)-shaped arrays
• do not have a channel_order parameter.

The new function signatures are:
det ret_ori_overlay(czyx, ret_max: Union[float, Literal["auto"]] = 10, cmap: Literal["JCh", "HSV"] = "JCh"):
def ret_ori_phase_overlay(czyx, max_val_V: float = 1.0, max_val_S: float = 1.0):

I have tested the new ret_ori_overlay on the example datasets (to check the lazy-computed dask arrays), and I've tested both new functions in CI.

Notes:

• @edyoshikun, earlier I thought that you'd implemented ret_ori_phase_overlay with JCh, but I now think that this case is covered by ret_ori_overlay with the JCh option.
• I have used this PR to clean up many of the unused pieces of colormapping code across recOrder. All of the visualization now lives in recOrder.io.visualization, and I anticipate this code will move to iphub.

this looks great! This merges the functions as we discusses and tees us up to for the porting to iphub and easier generation of these visualizations.

I originally had set it up to do np.min(retardance), but maybe the right thing to have here is to clip with (0,max(retardance)). What do you think?

[talonchandler]

I think the current behavior is an okay start. I think iterating on good default will require testing across a wide range of datasets. I'd like to do this, but I'd vote to keep the scope of this PR tighter.

LGTM! Thanks for unifying the implementations @talonchandler
