Ability to see if validator modified data

[HaroldStruwig]

What version of Ajv you are you using? v8.6.3

What problem do you want to solve? I want toknow if running the validator has modified the data or not without needing to do a comparison of the data after running the validator myself.

What do you think is the correct solution to problem? It can append a property dataModified as a boolean to the validator function similar to errors.

Will you be able to implement it? If I get a reference on where best to make the change yes.
