Feature Request - controlling dimension name in odc.stac.load

[harryle95]

AFAIK, the dataset is created from mk_dataset function which creates the coordinates from odc.geo.xr.xr_coords. This function allows for controlling the dimension name using the dims parameter, a feature unavailable currently at the loader level. Hoisting this parameter to the level of the load function would provide some control over the unpredictability of the dimension name. I am happy to help implementing this feature if people think this is useful.
