v4.0.0

• Breaking change: Now requires at least Node.js 12.x (somewhat following the LTS of Node.js itself)
• Dependencies: Moved to newer @voxpelli/semver-set module, which has fewer sub-dependencies and is now typed
• Dependencies: Created new list-installed module, replacing read-installed in this module, making it natively async as well as adds types
• Dependencies: Moved to read-pkg instead of read-package-json, making it natively async as well as adds types
