better sequencing

[Koeng101]

this implements functionality for handling sequencing data better.

• First, nanopore sequences are dual barcoded, and if they have a well, they are filtered out. The dual barcoded wells are then megamashed. All this data is saved to a different fastq file.
• This outputs reads (fastq) and a wellsToTemplate csv file.
• Those two can be used as an input to generate pileup files for each template.

Pseudo-code would be:

SequenceAnalyze(reads, templateMap, primerMap) (filteredReads, wellsToTemplate)
GeneratePileup(filteredReads, wellsToTemplate) map[well]pileup
