CRAN preparations

• https://cran.r-project.org/web/packages/submission_checklist.html

Things to do/check

• R CMD check --as-cran
• Please ensure that R CMD check --as-cran has been run on the tarball to be uploaded before submission
• Add DOI to Zarr publication(s) in package Description
• As a general rule, neither data nor documentation should exceed 5MB (see dog.ome.zarr is 6MB and .* files through lots of check notes. #87 )
• If running a package uses multiple threads/cores it must never use more than two simultaneously (may need to modify recent tests added in Read/write in parallel #91 )
• Packages which use Internet resources should fail gracefully with an informative message if the resource is not available or has changed (and not give a check warning nor error). (may require changes in HttpStore)
• Update GH Actions to run on Ubuntu, Mac, and Windows using an os strategy matrix

Working on a bit of no internet grace. Probably some more to do yet.

With #93, we are pretty close to ready to go. I want to do a bit more testing without internet and we'll need to reduce the size of the demo data. There are two ways to do that -- either make it a download or reduce its size. Will comment on that issue about that.

[dblodgett-usgs]

With what I just pushed, I think we should call the http error issues resolved. There is now only one NOTE:

❯ checking installed package size ... NOTE
    installed size is  7.5Mb
    sub-directories of 1Mb or more:
      extdata   6.3Mb

I'll kick off a few more checks here and see if anything surfaces.

Looks like a few things are picked up by the cran winbuilder.

(note that I changed the description temporarily so it had me as maintainer so I could get the emails about the test)

Nothing crazy in there.

Two notes from the winbuilder still.

With what I just pushed to #124 -- I only see two notes.

One is related to urls with illegal "[" characters in them -- I don't see how we can change them without just removing documentation for those methods.

The other is related to the word "Zarr" not being recognized.

I think we are probably basically ready to submit to CRAN but a high level review of introductory documentation and caveats about how the package is new / in development would be good still.
