Replace all report Dicts by OrderedDict

[fhagemann]

Addressing the issue legend-exp/LegendMakie.jl#29 (comment):

The peaks are always plotted in reverse order (from highest energy peak to lowest). Unsure how much work this is, but it would be cool if they were plotted from lowest to highest peak position.

This is due to the report being a Dict which is by default unordered.
How, such reports will be OrderedDict to preserve the order of the individual reports.

Note: this PR introduces a new light dependency of OrderedCollections.

Perfect, thanks! This will make plotting much nicer.
Did you test all functions on data? Otherwise this is for me ready to be merged

[fhagemann]

No, I did not test this yet on data, but I will within the next hours.

[theHenks]

I tested the energy part and verified that it works. Let's merge!
