Adds Position.compute_pyramids

Sorry if I'm being a pain in the neck during this review, I think iohub follows higher standards than some of our other code. I hope my requests make sense.

No I prefer this haha, I'm learning a lot from you so I think it's a good thing tbh.

I think we are very close! I'm not fully done reviewing the PR, but before I forget - it looks like _delete_pyramids deletes the zarr entries, but does not modify the ome metadata. Please extend _delete_pyramids such that it leaves a proper ome zarr store, even if you don't decide to recreate the pyramid levels

@ieivanov I had to make some adjustments due to 972aea1 (#348). Ready for re-review.

I think this PR looks good! Sorry, I'll change my mind on one thing - we should rename _initialize_pyramid back to initialize_pyramid. This way we are not introducing a breaking API change in this PR. Plus, the method may be useful if folks want to use iohub to initialize the pyramid structure and create ome metadata, but then compute them some other way.

Before we merge I'd love to get a review from @JoOkuma.

We should also refactor czbiohub-sf/biahub#12 to use these latest changes - this will tell us if we've gotten the API right.
