fixed pyomo release compatibility issues

[ddceruti]

So I tried to install romodel and noticed pyomo version compatibility issues:

1. pyomo==6.0 does not require pytulib -> added to requirements and setup.py
2. pyomo==5.7.3. does not support ScalarBlock -> latest commit does not work
3. pyomo 6.4.2 throws an error in romodel/uncparam.py constructor AttributeError: 'IndexedUncParam' object has no attribute '_index'

Therefore I updated setup.py and requirements with pyomo == 6.0 and pyutilib. Works on windows 10 and python 3.10 w_th gurobi.

Additionally updated the version to the latest romodel release v0.1.0

Additional info on the ScalarBlock commit: #1 which causes #2 due to pyomo >= 6.0 defaulting to latest 6.4.2 release.

Thanks a lot for this. I'm going to contact Johannes and see if he has time to review this.
