single scene loading

While loading datacube is great, it involves regriding systematically and I notice that dev/scientists in my company need to have the option to sometimes load a single scene with the original grid (as an xarray object).

I feel like doing it using your tech stack (obstore, async-geotiff, rustac) would be straight forward so I put together a rough proof of concept here:
https://github.com/developmentseed/lazycogs/pull/79

know this could also live in a wrapper library, so before spending time polishing the implementation, I'd love to hear your thoughts on whether this fits the project's scope and whether you'd be interested in such functionality.

Start by reviewing the rough proof of concept in developmentseed/lazycogs#79 and the project's existing datacube-loading behavior. The issue first needs a scope decision: whether loading a single scene on its original grid as an xarray object belongs in lazycogs or a wrapper library; done means that scope and intended functionality are agreed before implementation is polished.
