Add option to specify equality predicate for compare_values and provide a more sensible default (PSY)

[GabrielKS]

Companion to NREL-Sienna/InfrastructureSystems.jl#387, see discussion (including of backwards compatibility) there.

Tests are failing in CI due to the dependency on the IS companion branch.

I think the better implementation for sophisticated users is to implement

IS.compare_values(
     match_fn::Function,
    x::T,
     y::T;
     compare_uuids = false,
     exclude = Set{Symbol}(),

and forward

IS.compare_values(
    x::T,
     y::T;
     compare_uuids = false,
     exclude = Set{Symbol}(),

to

IS.compare_values(
 IS.isequivalent,
    x::T,
     y::T;
     compare_uuids = false,
     exclude = Set{Symbol}(),
