Initial custom particles, and a custom particle type and factor for friendship particles (heart and fire)

Small refactor to playerData args, and a fix to prevent "" blank player from being in every entitychatdata. It should only exist with migrated data. Also made the old legacy JSON properties disappear after saving this new data structure.

Fixing EntityChatDataLight, to correctly inflate from the full EntityChatData instances, including the current playerData.

More refactoring around PlayerData and player-based friendship. Also, adding in migration of data from entity-based friendship to player-based.

Large refactor of EntityChatData, EntityChatDataLight, and ChatDataManager. Separating these into smaller, individual files, to make it easier to maintain.

Fixing deploy scripts for both Modrinth and CurseForge

1.1.0 Release w/ Lead behavior

See merge request !16

Don't force path aware entities to look at the target while navigating a path (this breaks their ability to jump)

Switch from HashMap to ConcurrentHashMap to prevent an error when saving (while modifying the HashMap)

Ridable best friends now ignore Tameable entities (dogs, cats, etc... so you can right-click and sit them)

Best friends are now rideable! Right click with an empty hand. Large refactor of how MobEntity avoids targeting players when friendship > 0.

Reduced # of waypoints to 6 to 20. moveToTarget() every call to tick(). Add particles for debugging LEAD behavior. Switched back to FuzzyTargeting for finding valid positions.

Limit waypoint locations to 45 degree angle from current direction. Remove FuzzyTargeting (since it finds things too close to the entity to be useful). Fixed non path aware to use custom LookControls.

Fixing crash when displaying message on LeadPlayerGoal, to run the generateMessage in a scheduler (after 1 tick), and not in the Goal's tick method.

New LEAD behavior, to guide a player to a random location (and show message when destination is reached). Updated unit tests to add new LEAD tests.

Update README.md and fix spoiler sections

Converting spoiler tags to HTML instead of markdown, so more markdown converters will support it (i.e. CurseForge, Modrinth, and GitLab)
