Provide customization options for bounding boxes with CytoDataFrame image display

[d33bs]

Suggestion from @jenna-tomkinson . Sometimes the bounding box for images doesn't feel quite right and could use an adjustment to help view the overall context of the compartment images. See below for an example where the images appear to be "over-cropped" and cut out a portion of the object.

Maybe this could come in the form of a parameter passed to the CytoDataFrame as bounding_box_adjustments=(left, top, right, bottom) (+/- integers for making those adjustments where desired from the relative bounding box dimensions).
