Update electrolyzer models

Update electrolyzer models

Some projects have required changes or additions to electrolyzer models that have not made it into the core H2I codebase.

Proposed solution

We should update our electrolyzer models in H2I using what exists in side branches or project code.
This includes PEM, alkaline, and SOEC electrolyzer models of varying condition.
We can make these electrolyzer models use base classes and other productive organizational methods to decrease overall code complexity and increase maintainability.

For more details on expected inputs and outputs, see these notes from a current project partner:
Electrolyzer

• Electrolyzer type
  • PEM, Alkaline, SOEC, etc.
• Performance
  • Energy intensity load curve
  • Turndown limit
  • Ramp rate
  • Water consumption
• Cost
  • CAPEX
  • Fixed annual OPEX
  • Water consumption variable cost
  • Overhaul

Alternatives considered

We considered adding these electrolyzer models directly to the electrolyzer repo as that would make a large amount of sense.
However, we will instead update the electrolyzer models here to replace those that currently exist in H2I, ensure the updated models work for our purposes, then port those to the electrolyzer repo when appropriate.

Additional context

These electrolyzer models have been developed by and are useful for multiple projects.
