v0.0.7

This release of FIRE will be more robust for denovo assemblies.

Some feats:

• Save the Fiber-seq data in cram format
• Replace ucsc utilities with bigtools
• Replace some bedtools opts with gia
• Switch to polars for coverage calculation
• Rename config options to uppercase variables
• fix #28 incorrect counts in a plot
• fix #26 so that fire appears to be deterministic now; however, this is not yet guaranteed.
