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.

Do note that the sale on the Premium version will be ending on the 11th, which is tomorrow.

* 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
