If the contact in zoho campains is unsubscribed - subscription is not working.
Upon investigation I found this support post https://help.zoho.com/portal/en/community/topic/resubscribe-via-custom-form
where it is suggested that using donotmail_resub=true param would solve this issue.
Since this is an undocumented param it could change in the future.
Is it possible to simply add an optional array of params that will be merged into the API params in listSubscribe method of ZohoCampainsApi. It will make it flexible enough for future changes.
