    the problem is that files references by an include tag
    in PRJ files may contain content of prj-classes that are
    required to start in OGS6 object. If the included file is not read
    in, but only referenced, the simulation still works as the content
    is in the referenced file but not in the OGS6 object. Here, get_status
    would thrown an error.

    add an active field for include tag
    update active field for prj-classes to handle includes

[bugfix] make all OGS6 benchmarks work.

Closes #70, #63, and #60

See merge request !54

    add tortuosity and curve to the object
    to generate

[ci] exclude benchmark test pipeline from ci but run locally

Closes #69

See merge request !52
