ENH:binary decomposition_type option

[dalyw]

Use Case

If using eeco with an existing MILP, it would be useful to be able to create a MILP rather than a MINLP when callingcalculate_cost with a decomposition_type

Solution

In addition to absolute_value option for decomposition_type, can add "binary", making a binary variable indicating when exporting vs importing, and creating the import and export consumption variables based on that

Then add support for "binary" as an argument to ut.decompose_consumption()

Alternatives

Could consider other decomposition strategies as well or different means of creating binary variable
