Add pysam to the workflow/envs/mapdamage.yaml

[ZoePochon]

As MinLuke reported in issue #131, newly created conda environments don't work on the mapDamage step because they don't find pysam.

A quick fix is to add pysam in the workflow/envs/mapdamage.yaml like this:

channels:

• conda-forge
• bioconda
• defaults dependencies:
• htslib<1.15.1
• mapdamage2
• htslib<1.15.1
• parallel
• samtools
• pysam

worked for him and for me

Can confirm the issue!

I close it since the issue was fixed in the previous PR
