Version 1.0.1

Adds the GetPermalink method.

Version 1.0.0

Primary namespace of the library is fully documented.
CI/CD works from the release branch. Uploads a NuGet package and deploys the documentation to Github Pages.
All features of the Astronomy Picture of the Day API by NASA are fully functional.

First NuGet release

This is the first NuGet package release. This version should have all the features of the 1.0 release but much less documentation. The package will be fully released once I've added more information to the README and more documentation, with examples.
