Adding the basic functionality of FilledHistogram class

[Choklatier]

Summary

This pull request introduces the following changes

• Added a FilledHistogram class that takes in bin_edges and bin_heights instead of "values" and weights.
• The FilledHistogram objects can be added to HistogramPlot objects the same way Histogram objects get added.
• New helper function has been added to be used for FilledHistogram uncertainty computation.
• HistogramPlot plot method has been modified to act differently based on the Histogram type.

Relates to the following issues Probably the structure should be revisited to get rid of some helper functions and copy of the "divide" method Need to implement error handling (throwing and catching stuff) !

Thanks @Choklatier! I think with adding this there are two approaches, extending the current Histogram class to support bin heights and edges or by defining an extra class like you have done here. I'd maybe be more partial to having it all within the original class but that's just personal preference. But I notice with the current setup that there is quite a bit of shared code between the two classes in the __init__ , so maybe a better approach is to define a histogram base class and have the two types of histograms inherit from them to reduce the amount of shared code?

Thank you for the comment! I agree that there is a lot of shared code in the __init__ and also the divide method is copy pasted since it should exist for all histograms. Do you think it is better to have only one Histogram class and handle the differences in the constructor?

Yeah, if that's good with you I think it would be nice that way, just determine which is which based on the constructor arguments

Hi @Choklatier. The PR looks already really good! I just have two comments, mainly about some service stuff.

• Could you please fix the linting and pre-commit issues in the PR?
• Could you also please add tests for your new functionality?
• Could you add a changelog entry?

Once this is done, I'm happy to make the final review and merge it

I will add the new modification suggested by @zcapjdb and then I'll try to write some tests for the new functionality! I'll let you know if I figure out how to fix the linting and pre-commit issues!

@afroch I believe that each point is done now. Let me know if I missed something or if there is an issue!
