Refactor filegenerator to use functional options for configuration

[c-pius]

Description

Right now we have filegenerator and reuse-filegenerator which is a decorator on the former. The more idiomatic way in Go would be to move both into the same package and use functional options to configure reuse on top of the plain file generator.

It may look something like the following:

generator, err := filegenerator.New(
  kind,
  fileSystem,
  contentProvider,
  fileGenerator.WithReuse()
)

Figuring out the proper typing and structuring (e.g., with the decorator pattern) may be tricky.

Reasons

Further increase the quality of the project.
