Add support for EPIC v2

[Nicklas Nordborg]

The EPIC methylation chip has come in a new version. The number of probes is different and there are several new probes and also many of the old ones that have been removed.

Our analysis depends on two files with metadata: EPIC.hg38.manifest.tsv and EPIC.hg38.mask.tsv. For the new chip version there are new files that should be used. We need to implement support for this in our pipeline so that it is possible to configure different metadata files (in reggie-config.xml) for different chips and to automatically select the correct files when creating the job script.
