The gcnv contig_ploidy wrapper hardcodes config paths

[Nicolai-vKuegelgen]

Describe the bug
The wrapper for gcnv contig_ploidy contains hard-coded config sections (see below) but is uactually sed by different steps (helper_gcnv_model_targeted and helper_gcnv_model_wgs)

From snappy_wrappers/wrappers/gcnv/contig_ploidy/wrapper.py

par_intervals = snakemake.config["step_config"]["helper_gcnv_model_targeted"]["gcnv"].get(
    "path_par_intervals"
)

To Reproduce
Steps to reproduce the behavior:

1. Run the helper_gcnv_model_wgs step

Expected behavior
The wrapper script should automatically determine whether the targeted or wgs step is being run.

The wrapper should not determine anything but remain oblivious of its context. I'd rather factor the config access out and make the par_intervals a parameter, i.e. an entry in params.args. I.e. the steps calling this wrapper should be in charge of producing the correct par_intervals value to hand off to the wrapper.

Sounds like a better solution, I have so far only 'hotfixed' this by adding a "helper_gcnv_model_targeted" config section to my WGS projects.
