Add flag to give alternate barcode call when running in single/double barcode mode and using --annotate_files

Readucks v0.0.2

Default parameters and results now closely mimic porechop.
From a single test dataset (more testing coming) with default parameters, readucks:

• gives ~0.8% less precision (slightly higher miscalling of barcodes)
• gives ~4% more recall (more barcodes classified)
• runs ~4x faster
• requires ~1/80x RAM
