Custom variables with tokens

@Coco974, fixed the issue, created patch.

Hello,
It seems that this function was accidentally deleted.
It ensures that the tokens used in custom parameters do not infringe the GDPR (prohibition on the transmission of private data).

I added this method.
It is based on the same code as the Matomo module.

I am pushing a fix and will generate a new release quickly.

THANKS !
