FIX: fix problem remove "\\" -> with the residu "\" -> i don't know why it does that -> "nf-core/imcyto" has that

Started to work on the detection of broken subworkflows + Updated DSL1 to DSL2 with multiple emits problem fixed

Adding subworkflow to new code + added negation condition in the creation of channels locally in subworkflows

Moved the conditions to the outside of the cluster in the case of one condition in cluster + added the creation of empty channels

Added removing the empty conditions on the outside of the clusters and added the functionnality groupping together conditions inside the clusters

Added loads of functionnalities to try add the converter -> checkpoint before trying to duplicate multiple calls
