Add basic JSON support

[albertpastrana]

By applying this commit the anon tool will be able to read, anonymise and output basic JSON files.

It currently only supports one level JSON fields.

Some small refactor has been done and it's more than probable that the solution could be a bit DRYer, but don't have time to do so.
