Added Sort for peakpos based on ADC energy value

[RyutaroMatsumoto]

In simple_calibration.jl added Sort for peakpos based on ADC energy value to avoid sorting malfunction, which sometimes happens and leads to wrong calibration results.

Thanks for this PR.
Some comments from my side:

• could you replace @info with @debug so that the logging is shown in debug mode only (or add a verbose keyword to omit the @info output)?
• is this the correct place to put it? I somehow feel like this should go directly into RadiationSpectra applied to the output of peakfinder before returning it (?). This way, everybody using RadiationSpectra.peakfinder could profit from this.

Looking at LEGEND analysis:

• @theHenks would this interfere with finding the Tl208 FEP vs. finding the pulser peak if we sort them by ADC?

Hi, this for the feedback. This is work in progress and will not be merged like that into co60
