v1.0.11_preview-1

This is an early preview release of a new feature expected in version 1.0.11 for performing Relative Efficiency analysis.

There are two new tools, "Isotopics from peaks" and "Isotopics by nuclides". The former is fairly complete and appears to be working well for a number of tested use-cases, while the latter is still under active development and may not make it into the 1.0.11 release.
Documentation is not yet available for either tool.
