Task 3b. Add OMIM data

[yocra3]

Add data from OMIM for epimutations annotated to genes, based on Illumina Annotation.

[yocra3]

Gene data should be reduced. Each gene should be reported only once and separators should be rethink. If there are no genes, maybe we do not need to print anything.

There is an issue with that, if we try to generate a table per cpg id then it would be complicated to track which genes belong to which cpg as the genes are annotated using the cpg id and not the coordinates.
