phoenix_v0.4.3

This is a minor developmental release that fixes some potential bugs when using manta, primary changes are:

• Swapped manta/1.6-GCCcore-8.2.0 with manta/1.6, the GCCcore-8.2.0 version runs into odd bugs with high coverage data
• Delly now uses the openMPI module and is now "sample" threaded, meaning that is uses two threads during somatic variant calling. This speeds up variant calling and can potentially allows some instances to get past the split-read alignment step and reach completion
