Path to supporting Julia 1.X

[logankilpatrick]

Hey @ihnorton any interest in getting this package updated to work with Julia 1.X? I think having it in the JuliaHealth Org or Open Slide Org itself could be a cool thing to do. I am working with the Open Slide folks in a limited capacity so could help start the dialog if there's interest.

Hi @logankilpatrick,

Blast from the past here... I took at quick stab at updating in #5, and will poke around some more when I can (spare time is quite limited, unfortunately). Also happy to review PRs and give write access to anyone who's actively interested in updating. Moving it to the openslide org would be really neat, but until there's an active maintainer that might be premature.
