Move python scripts into bin dir

[adamjtaylor]

Your nextflow tower run ended with the error

python3: can't open file '/.nextflow/assets/ncihtan/nf-htan-qc/modules/download_synapse.py': [Errno 2] No such file or directory

In the relevant process you put the path to the script as

nf-htan-qc/modules/download.nf

Line 12 in b8c1298

python3 ${baseDir}/modules/download_synapse.py ${synapse_id}

A more robust approach to pointing towards scripts in Nextflow is to

• Put the script in the bin directory of the workflow repo
• Ensure it has a python shebang at the top (#!/usr/bin/env python)
• Ensure it is executable with chmod +x <path-to-script>
• Evoke it without saying python eg just download_synapse.py <samplesheet>
