Possible updates so Finemapr works with Finemap version 1.3.1

• mainly updates to how input files are created, but there is still a bug because finemap 1.3 cannot read the z-file.

Hi Kathryn,

Thank you for your contribution. I haven't worked on this project for a while. So I will spend some time to recover my design rules to keep all fine-mapping programs work together within my R interface.

Some thoughts:

• we might want to have several versions of a program, e.g. finemap, to be supported;
  • Otherwise, always stick to the latest version and keep old classes, e.g. "FinemaprFinemapV1" for back compatibility and without any further support.
• if I remember correctly, I aimed to give the same column names to, e.g. "snp" for genetic variant, inside my package, so generic functions in my package can be applied across programs/classes

Best, Andrey
