Add injection optimization tutorial

Is your feature request related to a problem? Please describe.
It would be nice to show how you can use CRM results to optimize water injection

Describe the solution you'd like

1. Start out with production and injection histories
2. Run CRM to get the gains from injector to producer
3. Set a water injection budget, limits on how high or low each injector can go, etc
4. Optimize oil production given these constraints

Describe alternatives you've considered
This could become a feature of the library if it gets enough interest.
