CRAN preparations

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

Things to do/check

• [x] R CMD check --as-cran
• [ ] Please ensure that R CMD check --as-cran has been run on the tarball to be uploaded before submission
• [x] Add DOI to Zarr publication(s) in package Description
• [ ] As a general rule, neither data nor documentation should exceed 5MB (see #87 )
• [x] If running a package uses multiple threads/cores it must never use more than two simultaneously (may need to modify recent tests added in #91 )
• [x] 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)

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

[dblodgett-usgs]

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.

Possibly misspelled words in DESCRIPTION:
  Zarr (3:19, 20:31)

Found the following (possibly) invalid URLs:
  URL: https://cran.r-project.org/web/packages/roxygen2/vignettes/rd-formatting.html
    From: README.md
    Status: 200
    Message: OK
    CRAN URL not in canonical form
  The canonical URL of the CRAN page for a package is 
    https://CRAN.R-project.org/package=pkgname

The Title field should be in title case. Current version is:
'Slice into Zarr arrays in R'
In title case that is:
'Slice into Zarr Arrays in R'

Found the following \keyword or \concept entries
which likely give several index terms:
  File 'ZarrArray.Rd':
    \keyword{(default),}
    \keyword{False,}
    \keyword{Object,}
    \keyword{String,}
    \keyword{True,}
    \keyword{provided,}
    \keyword{stored,}
    \keyword{value,}

* checking HTML version of manual ... [12s] NOTE
