ome.ts: update with ome-zarr 0.5

[joshmoore]

RFC-2 has now been adopted. In preparation for the OME-Zarr 0.5 release, this PR wraps the NGFF metadata in the Zarr metadata within an "ome" block. This checks for that block and if it exists unwraps the necessary metadata if the Zarr version is 3.

Originally opened as #616

Thanks!

[jbms]

Can you fix formatting with npm run format:fix ?

[joshmoore]

TIL:

npm i prettier
npm run format:fix
