Avoid using comparison to stringified integers when using enums in configuration of algorithms

[sebouh137]

Is your feature request related to a problem? Please describe.
Yes. If enums are used as parameters of algorithms, JANA converts the parameters to integers and then into strings. It is therefore necessary to create code like this, as merged in PR #1502 , which compares string parameters to string representations of integers, like this:

EICrecon/src/algorithms/calorimetry/ImagingTopoClusterConfig.h

Line 42 in 2413820

if (s == "etaphi" or s=="0") {

Describe the solution you'd like
Something that causes these enum constants to be converted to human-intelligible strings instead of string representations of integers

Describe alternatives you've considered
N/A

@nathanwbrei Maybe you're interested in this. Despite a dedicated ostream operator which should make this satisfy is_serializable with precendence over the underlying_type, we are still seeing enums go to integer string representation.

I'm definitely interested. I've created a corresponding issue in the JANA tracker here: JeffersonLab/JANA2#318
