WIP

Description

Two new modes for generating one file per operation. Thoughts?

Generated files for petstore.yaml in mode TAGS_OPERATIONS will be:

src/
├── health
│   ├── health-check.ts
│   └── index.ts
├── models
│   └── ...
└── pets
    ├── create-pets.ts
    ├── delete-pet-by-id.ts
    ├── index.ts
    ├── list-pets.ts
    └── show-pet-by-id.ts

Generated files for petstore.yaml in mode TAGS_SPLIT_OPERATIONS will be:

src/
├── health
│   ├── health-check.msw.ts
│   ├── health-check.ts
│   └── index.ts
├── models
│   └── ...
└── pets
    ├── create-pets.msw.ts
    ├── create-pets.ts
    ├── delete-pet-by-id.msw.ts
    ├── delete-pet-by-id.ts
    ├── index.ts
    ├── list-pets.msw.ts
    ├── list-pets.ts
    ├── show-pet-by-id.msw.ts
    └── show-pet-by-id.ts

That's a good idea.
However, adding more modes would affect many cases, and would also increase the number of elements that would need to be covered for future feature additions.
Taking that into account, I couldn't find a rational reason to add this mode.
