Support for symfony_mailer

Hey guys!

Just chatting with NikLP who mentions that the govuk_notify module is not compatible with https://www.drupal.org/project/symfony_mailer → .

Over in the LocalGov Drupal world, our localgov_workflows_notifications module now depends on symfony_mailer (https://github.com/localgovdrupal/localgov_workflows/blob/1.x/modules/lo...)

If they don't work together, that poses a bit of a choice for LocalGOv Druapl councils.

What would we need to do to fix that? Is it a lot of work?

Cheers

Finn
