Find GWAS variants that are in high LD with QTL variants

1 2	findGWASOverlaps(gene_snp_pairs, gwas_catalog, vcf_file, max_distance = 1e+06, min_r2 = 0.6)

`gene_snp_pairs`	QTL SNP and variant pairs (required columns: gene_id, snp_id)
`gwas_catalog`	GWAS catalog data_frame from the importGwasCatalog function (required columns: snp_id, chr, pos)
`vcf_file`	Genotype data
`max_distance`	maximal distance between the qtl variant and the GWAS variant
`min_r2`	Minimal R2 betweeb the QTL vairant and the GWAS variant
