Improvements to DM analysis pipeline, diffuse fitting and lightcurve analysis.
- Added fitting code to fermipy.diffuse module
- Improved fermipy.jobs to deal with analyses with multiple components
- Added capability to plot global minimum in castro plots
- Added spectra for dark matter decay to DMFitFunction
- Added code to split simulations into smaller batch jobs
- Added fixed shape lightcurve to correct TS_var computation
