Use ffizer as a linter

[davidB]

When persistence of variables inputs, will be done.
ffizer could be used like a linter/formatter to keep code uptodate with templates (by a "small" adaptation of ffizer apply or ffizer test-samples)

Possible integrations:

• Megalinter
• github-action (check only or apply fixes / make PR like dependabot)
• run ffizer on a set of local project, remote git project
