Prepare new compositions for database upload
prepare_new_compositions.RdCompositions consist of strains and percentages, where there can be multiple or single strains and the sum of each strain must be close to 1 (some tolerance is allowed). The composition is a descriptive identifier in the case of new monoclonal and polyclonal, where the monoclonal label is the name of the strain, and the polyclonal label is a formatted string of the number of strains and a unique, incrementing index. For example, "W2" is a monoclonal 'W2' composition and "2S_1" is a dual strain composition that we would need to collect more information about from the database. Monoclonal compositions are always considered legacy.
