Battenberg reference files for hg38

Reference files needed to run Battenberg, an algorithm for calling clonal and subclonal copy number aberrations from Next Generation Sequencing data. These reference files are appropriate when working with NGS data alighted to human reference genome hg38. If using hg19 aligned sequencing data or SNP array data, the reference bundle at the Oxford Research Archive (https://ora.ox.ac.uk/objects/uuid:2c1fec09-a504-49ab-9ce9-3f17bac531bc) would be more appropriate.
