Allow non-fixed allele ID MADC for some conversions #151
Description
Currently, all conversions from MADC to VCF require a fixed allele ID MADC file. Though, it is not required if the user is only extracting the target loci and if they do not need/want the ref/alt allele information.
- So, the user should be able to use a raw MADC file in this instance, and
- They should be able to upload a .txt file that has three columns (TargetID, Chrom, Pos) to account for the potentially unique named target locus.
