Adding a parameter for "check_prior" with susie_rss

[floutt]

I noticed that I was getting errors when using the ROSMAP-derived LD matrix on the Bellenguez summary statistics. Whenever I would run it I would get the following error

The estimated prior variance is unreasonably large. This is usually caused by mismatch between the summary statistics and the LD matrix. Please check the input.

In order to get around this I had to edit the Jupyter Notebook and manually change the check_prior parameter of the susie_rss function to F to get around this. I think that it would be useful to add a new parameter --check-prior to the susie_rss fine-mapping pipeline to deal with situations like this

Hmmm I wonder is the LD and the sumstat are matched correctly though? i.e. is the error msg was mistaken.

Let us keep this check mandatory for the time being until it turns out that it will be too resource intensive for the 1700 LD-Block
