Parse Floats from GtcToVcf in VcfToAdpc

[tlangs]

Description

If GtcToVcf spit out a VCF with InfiniumVcfFields.NORMX or InfiniumVcfFields.NORMY over 1,000, it VcfToAdpc would fail because the written-out float had a comma separating the hundreds and thousands place. Using the same DecimalFormat in VcfToAdpc fixes the issue.

Can you add a test for this (handling NORMX or NORMY > 1000)? Probably should just need to add an offending line to Test.gtc.records.csv.
