Consistent Converters

API changes

• The OffsetConverter expects two dictionaries now instead of the coefficient tuple. These are, conversion_factors with the slope relative to the NonConvex flow, and normed_offsets with the normed offsets relative to the NonConvex flow.
• The NonConvex attribute must be specified for one of Flow at the inlets or outlets of the OffsetConverter. min, max and nominal_value have to be specified for the same Flow.

New features

• OffsetConverter can now handle multiple inputs and outputs
• There are two methods available for the OffsetConverter to calculate the slope and normed offset relative to the NonConvex input given the min, max and the respective efficiencies/ratios, i.e. slope_offset_from_nonconvex_input and slope_offset_from_nonconvex_output.

Bug fixes

• Fix custom attributes of Sink, Source, GenericCHP and Converter components not being properly passed to base Node class

Other changes

• Unified (usage) documentation for OffsetConverter
• Remove approach to model cellular systems (was more confusing than it helped)
• Refine indexing of flows (period index was not needed).

Known issues

• Incompatible to numpy >= 2.0.0. This is because of Pyomo, but we have to enforce a lower version in our package.
