"Vcf" perl module changed name to VCF

[ericcrandall]

The package has changed its name, which has broken this script. I went through the code and fixed 3 instances where I thought it was referring to the Vcf Module. Nevertheless, when I try to run this script I get the following error:

usage: GLOB->new() at ./rad_haplotyper.pl line 202.

This has something to do with the VCF package name change I think, but I'm stuck. I've tried using the manual cpan install as well as the conda environment. Both give the same error.
