Update WOperator import for SciMLOperators migration (#358)

* Update WOperator import from DiffEqBase to SciMLOperators

Downstream update for SciML/OrdinaryDiffEq.jl#3017 which moves
WOperator and StaticWOperator types to SciMLOperators.

- Import WOperator from SciMLOperators instead of DiffEqBase
- Add SciMLOperators >= 1.15 as direct dependency
- Bump OrdinaryDiffEqDifferentiation compat to include v2
