You might want to start looking at the GATK:

I'm not sure if it has exactly what you want, but it could be a good
place to start as a foundation/toolbox if you're looking to build such
a thing. From their website:

The Genome Analysis Toolkit (GATK) is a structured programming
framework designed to enable rapid development of efficient and robust
analysis tools for next-generation DNA sequencers. The GATK solves the
data management challenge by separating data access patterns from
analysis algorithms, using the functional programming philosophy of
