Option to set minimap2 -I flag

[fellen31]

Hi,

Ran into this error while trying to run hapdup:

I suspect it could be because of the default minimap2 -I flag being too small (4G)?
If this is the case, maybe an option to specify this could be added, or adjust it automatically depending on genome size?

Thanks!

Very likely that's why, will take a look soon.

Can confirm changing -I fixed the problem.

Thanks. I added the fix to this docker image: mkolmogo/hapdup:0.6-iss13. And it will be incorporated into the next release.
