This has to do with issue #390

@blankenberg?

The biggest issue here has to do with the fact that sicer (GenomeData.py) itself needs to be modified to work with each new genome build. Apparently I wrote to the sicer authors around 2011 (see e.g. here) to see about them updating sicer to accept .len files instead of having hard coded lengths. I'm assuming this hasn't been done.

If we are going the modification route, I would suggest modifying the underlying sicer code to accept .len files instead of just adding more hard coded values. This should be really quite easy to do.

If so, it is probably worth creating a separate github repo to track the changes and making conda recipes, etc. Would need to double check the licensing of course as well.

Unfortunately, I would not suggest merging this PR as-is.
