PHP warning

[viliusle]

Summary

Plugin is defining few constants: RED_DEFAULT_PER_PAGE & RED_MAX_PER_PAGE in admin section, but using in other sections too. This is not problem usually, but in some cases error below will be thrown.

PHP Warning: Use of undefined constant RED_DEFAULT_PER_PAGE in /wp-content/plugins/redirection/models/redirect/redirect.php on line 946
p.s. same with RED_MAX_PER_PAGE

Steps to reproduce

If other plugin wants to get redirects, like:

$Red_Item = new Red_Item([]);
$redirects = $Red_Item->get_filtered([]); //method works nice outside of plugin, but error will be thrown here

Environment

WP: 6.4.3
Plugin: 5.4.2

p.s. no need to reply, I already fixed it by editing plugin and moving these constants to main plugin file. But I might need to update plugin, other people may have same issue.
p.s.s. plugin is amazing, thank you.
