Refactor TrailFollower and ElytraFlyPlusPlus modules

TrailFollower received major refactoring: settings were reorganized, new enums for flight and path modes were added, and logic for following trails in opposite dimensions was introduced. Chunk validation and trail following logic were improved, and webhook support for logging was added. ElytraFlyPlusPlus received minor fixes to pitch/yaw slider ranges, collision/stuck detection, and ground jump logic for improved flight control. Credits to Jeff.
