This update provides a few bug fixes and adds support for 1.21.5.
Please note that Paper has not released 1.21.5, this was tested with Spigot.

* Added 1.21.5 support
* Bumped required PacketEvents version (It'll update automatically, but will need server to restart, LD will likely break until it restarts)
* Added 'flying' permission group, eg "libsdisguises.disguise.flying" would get you bat, parrot, so on. Not enderdragon!
* Fixed issue with option permissions when used on a disguise with an underscore in its name
* Fixed issue when disguises provided via configuration or external plugins had trailing spaces and did not parse properly
* Fixed an issue with some disguises not saving properly
* Fixed periods (.) not being escapable via backslash (\)
* Fixed disguise scaling not updating properly
* Fixed saved disguises loading even if disabled
* Fixed saved disguises not saving even if enabled
* Fixed Lib's Disguises not throwing an error for unsupported versions of Minecraft
* Fixed wrong message displaying when PacketEvents was not up to date
* Fixed 'setReplaceSounds' not existing as a parameter, this toggles if a disguise has its sounds replaced or not
* Internal improvements and handling of very minor importance, largely in relation to the 1.21.5 update
