Add support for multi-modules maven project as currently the scanner can only process a maven project

[cmoulliard]

The code of the project should implement something like this

        //If running across all projects, iterate and parse source files from each project
        Map<MavenProject, List<Marker>> projectProvenances = mavenSession.getProjects().stream()
          .collect(toMap(Function.identity(), this::generateProvenance));
        Map<MavenProject, Xml.Document> projectMap = parseMaven(mavenSession.getProjects(), projectProvenances, ctx);
        return mavenSession.getProjects().stream()
          .flatMap(project -> {
              List<Marker> projectProvenance = projectProvenances.get(project);
              try {
                  return listSourceFiles(project, projectMap.get(project), projectProvenance, styles, ctx);
              } catch (DependencyResolutionRequiredException | MojoExecutionException e) {
                  throw sneakyThrow(e);
              }
          });
