HERON dependencies have been updated to pip install newest DISPATCHES version (still as an optional dependency)
HERD restructured the build function that creates the Pyomo Multiperiod model to match the newest DISPATCHES release. It now creates a Multiperiod IDAES object that can handle stochastic sets.
Python imports of the DISPATCHES package match the newest re-organization of the DISPATCHES repository.
HERD now uses an intermediate flowsheet_block method to avoid redundant creation of Pyomo Models; instead it creates one model per realization/scenario and for each (time, cluster, year) timestep within that realization it clones from the original.
Fixed error involving wrong NPV values when num_samples > 1. Regolded nuclearCase_Sine test because that was the only test with more than 1 scenario.

The following review must be completed by an authorized member of the Change Control Board.

[x] 1. Review all computer code.
[x] 2. If any changes occur to the input syntax, there must be an accompanying change to the user manual and xsd schema. If the input syntax change deprecates existing input files, a conversion script needs to be added (see Conversion Scripts).
[x] 3. Make sure the Python code and commenting standards are respected (camelBack, etc.) - See on the wiki for details.
[x] 4. Automated Tests should pass.
[x] 5. If significant functionality is added, there must be tests added to check this. Tests should cover all possible options. Multiple short tests are preferred over one large tes.
[x] 6. If the change modifies or adds a requirement or a requirement based test case, the Change Control Board's Chair or designee also needs to approve the change. The requirements and the requirements test shall be in sync.
[x] 7. The merge request must reference an issue. If the issue is closed, the issue close checklist shall be done.
[x] 8. If an analytic test is changed/added, the the analytic documentation must be updated/added.
[x] 9. If any test used as a basis for documentation examples have been changed, the associated documentation must be reviewed and assured the text matches the example.
