Feature/byer3/well constraints

[tjb-ltk]

feat: Formalize definition of well constraints to

1. allow more than 2 constraints per well
2. minimize restrictions on rate type
3. allow production/injection constraints for one well (future capability)
4. improve code for constraint processing in general and also needed for well estimator
5. current implementation requires schema changes, script provided scripts/convert_well_schema.py

ToDo

1. add validation based on current implementation rules
2. add control switch logging
3. organized constraint hpp and cpp so all methods are in similar order
4. submit new input files

Subsequent PR's based on this PR

1. New constraint activation/test models (Liquid, needs phase name validation, single phase mass rate, ...)
2. change balance equation scaling, should be current rate?, not constraint rate, this will change results but will clean up residual check code
3. well estimator
4. well head pressure constraint
