Move calibration into mzLib

[leahvschaffer]

As calibration is further improved and tested (especially for topdown data), if it was part of mzlib then these improvements could be used in proteoformsuite

Yeah. The inputs would be identified peptide/proteoform spectrum matches, that come from any source. Could come from a MetaMorpheus search, or use a search result from the northwestern software. I think it's workable, I'll think about how to move it from MetaMorpheus in the best way.
