v0.2.0: Merge pull request #4 from harmsm/main

Code now does:

• Simulation of experiments
• Processing raw reads (fastq through ln_cfu/condition)
• Independent modeling (extract that for each genotype independently)
• Hierarchical modeling (Bayesian analysis of theta together)
• Epistasis analysis
• Epistasis vs. [titrant] categorization analysis
• Various helpful plotting utilities.

Additionally, the API is now (roughly) stable. I antiquate no major changes to the simulation, raw-processing, or independent modeling code base. I expect to build out the hierarchical modeling codebase and clean up the utilities functions. None of these will be architectural changes, however, just minor refactors.
