Openmc-source-plotter

What's Changed

breaking changes as package no longer extends OpenMC classes. Instead it provides functions that require OpenMC objects to be passed in. Examples have all be updated so migration should be easy.

* change package to user functions instead of extending openmc classes by shimwell in https://github.com/fusion-energy/openmc_source_plotter/pull/39
* Converting material gamma emission plotting to function by shimwell in https://github.com/fusion-energy/openmc_source_plotter/pull/40


**Full Changelog**: https://github.com/fusion-energy/openmc_source_plotter/compare/0.6.8...0.7.0

What's Changed
* adding gamma spec image by shimwell in https://github.com/fusion-energy/openmc_source_plotter/pull/36
* added plotting methods to openmc.Settings by shimwell in https://github.com/fusion-energy/openmc_source_plotter/pull/37
* added axis type (log linear) and axis units (MeV, eV) to energy plot by shimwell in https://github.com/fusion-energy/openmc_source_plotter/pull/38

example plot, source energy distribution of DT source with DD, DT and TT reactions made using [openmc-plasma-source](https://github.com/fusion-energy/openmc-plasma-source) and [NeSST](https://github.com/aidancrilly/NeSST)
