3.0.0

• Updated workflows to WDL1.0
• Removed GenerateOutputMap task from bam to unmappedbam workflow because "if other lines in the header contain the characters @rg, they will be caught here. "
• Removed fc version of fastq2ubam because updates to Terra make working Data tables easier. Creating a seperate file with sample metadata isn't necessary.
• Added default variables to cram2bam
• Simplified pair2ubam workflow to accept one pair of samples at a time, making it easier for Terra users
