Description of feature
Currently, we encourage people to set --igenomes_base to use a local cache for reference genomes instead of downloading the assets for every run. However, this is not very obvious and many people don't do it.
It could be good to set a default cache location for iGenomes that is outside of the work directory, to avoid repeatedly downloading the same assets.
This needs to be visible as it could mean a lot of data. We need a sensible default path and also to log to the user about it.
