Always run all SV callers

[fellen31]

This PR always runs all SV-callers. This changes the output files for sample, e.g.:

svs/sample/HG002_ONT_B/HG002_ONT_B_svs.vcf.gz

is replaced by:

svs/sample/HG002_ONT_B/HG002_ONT_B_severus_svs.vcf.gz
svs/sample/HG002_ONT_B/HG002_ONT_B_sniffles_svs.vcf.gz

In addition, add a hidden parameter --publish_unannotated_family_svs was added. This will output merged family calls per caller. This parameter has been added to the samplesheet_multisample_bam_ont test, and for example outputs the following family files:

                "svs/family/FAM/FAM_hificnv_cnvs.vcf.gz",
                "svs/family/FAM/FAM_hificnv_cnvs.vcf.gz.tbi",
                "svs/family/FAM/FAM_severus_svs.vcf.gz",
                "svs/family/FAM/FAM_severus_svs.vcf.gz.tbi",
                "svs/family/FAM/FAM_sniffles_svs.vcf.gz",
                "svs/family/FAM/FAM_sniffles_svs.vcf.gz.tbi",
