[suggestion] Add LEO analysis option

[josephko91]

Hi! I was wondering if you guys had plans to add LEO to this package? I did some SP2 related work years back, and I remember thinking it would be great if all the Igor software was also available in Python. So I'm really glad to see a Python package for SP2 analysis has finally started!

I'm also potentially interested in helping out if you need help coding in the LEO analysis. Looking forward to further discussing if there is general interest in this feature being added!

Our future plans currently include incorporating lagtime and coating thickness calculations into PySP2. If you are interested in adding in LEO analysis to PySP2, we would be more than willing to work with you on a pull request to add this feature to PySP2.

Awesome! Glad to hear there are future plans to incorporate both. If I can find time, I am interested in getting involved.

@johbackm wrote some great code as a first step for the LEO fit (beam shape analysis) in PR #52.

Version 1.7.0 has a first version of LEO fits implemented by @johbackm !
