[argus] New port at version 0.1.0

[lucocozz]

• Changes comply with the maintainer guide.
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx.
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.

The current name conflicts with openargus using our naming guidelines of removing common prefixes/suffixes like open-, lib-, cpp-, etc.

However, we acknowledge that openargus is not a library and searching for "argus argument parsing in C" does show this library as the top result in Bing. There's also other existing argument parsing libraries with the same name (https://github.com/whexy/Argus, https://github.com/KageKirin/argus) which could lead to confusion for users.

We don't consider this a blocker, but we think your users would feel a lot better if, it had the GitHub org name prefix lucocozz-argus.
