Ph/re scale boqa raw log score

[hansenp]

I implemented the following method to re-scale the BOQA scores so that they can be combined with the variant score in Exomiser.

The boqaRawLogScores are calculated directly in BOQA from the four counts to avoid numerical instabilities.

This score has the following properties:

1. Exomiser compatible: The maximum score is always 1.0, the lowest is 0.
2. BOQA's ranking remains unchanged.
3. The original BOQA scores are somehow reflected in the transformed BoqaExomiserScore (which is not the case with rank scaled score).

Here is the distribution of scores across ranks for 3000 phenopackets from phenopacket-score for which BOQA ranks the diagnosed disease first.

To implement this, I added a function in BOQA BoqaPatientAnalyzer that provides the BoqaPrioritizer in Exomiser with unnormalized BOQA log scores. See here: P2GX/BOQA#32

Hi @hansenp is this ready to go now? If so, please set it as ready for review. Also, it needs to be merged into the boqa branch, not development.

@julesjacobsen I changed the base from develop to boqa. After that, I had to resolve a few conflicts. I resolved them and marked this PR as ready for review.
