No code changes - just tweaked the README and Tests.yml.

Added tvOS to supported platforms.

Update to Swift 5 (mostly so that I can use the 5.0 package tools format, and specify minimum os versions in the Packages.swift file).

Fixed a few Swift 5.0 warnings.

Added GitHub Actions support to the project. This will probably replace Travis when I get it playing nice with my general workflow.

Fixed a minor warning that Cocoapods was complaining about.

Updated podspec version no.

Enables iOS support for the podspec.
Uses compactMap when available.

Adds a podspec for use with Cocoapods.

More flexible handling of default values.
Better support for decoding URL and UUID items.

More unit tests.
Travis-CI integration.
Added the ability to have missing values filled in from defaults.

First version.
