Thermodynamics Calculations

[AnsbigetHildElarik]

Summary

Adds thermodynamics calculations to estimate overload duration and show as column in fitting view.

Notes

• I wrote this code 12 years ago for my own fitting tool so I've left in the ported js code for reviewers but it shoud be removed prior to merge.
• It would be nice to i18n the one message but I'm not sure how to make that happen, there is a comment in there about it.
• There could be better ways to accompish the pythonic/eos/fit things, happy to see that improved if possible.
• This could use some testing. I did some manual tests to verifiy the burnout times, they lined up fine and the math should be correct.
