Support for AwesomeCV (https://github.com/posquit0/Awesome-CV).
This is based on ox-altacv, with modifications for the macros and
structures supported by AwesomeCV. At the moment the following types
of sections are supported:
- CV_ENV "cventry" converts the section into a cventry environment.
- CV_ENV "cvskills" converts the section into a cvskills
environment. It must contain a description list, which gets renders
as the appropriate "cvskill" elements.
