27	* Replace ACF revisions hooks
28	*
29	* Since ACF 6.4+, ACF copy post meta to revisions using a new logic inside acf_copy_postmeta()
30	* That new logic uses the new acf_get_meta_instance('post')->update_meta()
31	* This bypass the historical acf_update_metadata() which called the hook: acf/pre_update_metadata
32	* This hook is important, as it's used by the Performance module to save compressed meta in the revisions
33	*
34	* The code below that replace ACF hooks is identical to the native ACF 6.4+ code found in:
35	* /advanced-custom-fields-pro/includes/revisions.php
36	*
37	* They have been simply rewritten to call our custom acfe_copy_postmeta() where needed
38	* acfe_copy_postmeta() then use the classic logic with acf_update_metadata() > acf/pre_update_metadata
