Heads up: 'from_email_address' option values are moving

Hi! I wanted to let you know that OptionValues for 'from_email_address' are moving to a new table.

Changes like this can be a hassle for extension maintainers, so we're trying to keep this as painless as possible by adding backward-compatibility adapters to core. Most Api3 and Api4 calls to this option group will still work (behind-the-scenes, the adapter will read/write from the other table and convert values from one format to the other). A few other commonly-used functions have also been adapted, see full migration notes here.

In the short-term, nothing needs to be done to this extension. I've run your unit tests locally and they all still pass. Here is a MR to add some code comments about future migrations. Other than that, this extension appears to be already compatible with the changes.
