fix(qsv): fixing issue where references didn't match

[newellf]

For a SplitReadContig, there was a case where the SV was a translocation but a reference check was not performed resulting in the incorrect breakpoint associated with the incorrect reference. Added a reference check

Description

In SplitReadContig, a reference (chromosome) check of the knownSV reference compared with the the proposed split read SV references was added.
