Merge branch 'jathenst/188-dep_scripts-unify-d-and-p-flags' into 'master'

Resolve "dep_scripts: Unify `-d` and `-p` flags"

This MR removes the separate `-d` and `-p` and combines them in one. `-d` was removed, specific dependencies are now set with `-p`. Therefore, the following options are available:

- `-p default:latest` for accessing the latest dependencies from the default profile
- `-p mercury@default:latest` for accessing the latest mercury dependencies only from the default profile

Closes #188
