CreateVerifyIDIntensityContaminationMetricsFile should handle scientific notation

[kachulis]

sometimes, VerifyIDIntensity will output values in scientific notation, which breaks CreateVerifyIDIntensityContaminationMetricsFile.

I think it would be easy to fix this, this regex

picard/src/main/java/picard/arrays/CreateVerifyIDIntensityContaminationMetricsFile.java

Line 85 in e38a205

final Pattern DATA_PATTERN = Pattern.compile("^(\\d+)\\s+([0-9]*\\.?[0-9]+)\\s+([-0-9]*\\.?[0-9]+)\\s+([-0-9]*\\.?[0-9]+)\\s*$");

just needs to be modified to match scientific notation as well
