/**
 * Ran into an issue with a WP site where I needed to change an ACF select dropdown into a real WordPress taxonomy. Wrote this to move the data from an ACF select to taxonomy. This will create terms from an ACF select (manually, have to get the data from the ACF field editing interface). Then it will go through all posts and apply the new taxonomy term according to the ACF select value that already exists on the post. 
 *
 * ⚠⚠⚠ WARNING ⚠⚠⚠
 *
 * This is not a professional migration thing. If you use this:

* Put into `functions.php` or as your own `mu-plugin` file.
* Run on a local installation first. If you can run locally and export your DB back to live, even better.
* No idea how it'd perform if you had thousands of ACF fields. It worked OK for me with 250 potential ACF select values.
