Dynamic Healthbar Colours and Insta-kill text

[radioactive-exe]

ADDED

• Aggression-based healthbar start colours - Neutral, Aggressive/Hostile, and Passive/Default
• Colours change based on entity state, e.g. if a neutral mob becomes angry, the healthbar colour changes
• Instant kill and regular kill text particle
• Logic for both specific uniquely behaving mobs and generic mobs to be compatible with most modded mobs
• Tamed mobs will always appear as passive
• Toggles in the config for both Aggression colours (separate for both the HUD and in-world) and Kill text (in the Particles tab)
• If Aggression colours are turned off, all mobs will use the default/passive colour. Only the start colours are altered, the end colours (if Dynamic Colouring is enabled) stays the same.
• If the kill/instakill text is turned off, regular number particles spawn for kills and instakills.
• Functional Utilities class, to house functional utilities like generic LERPing, etc. Currently houses the colour deduction logic.
• Added lang entries in en_gb and en_us.

CHANGED

• Altered TextParticle Codec sifting to allow strings to be passed to the particles too

REMOVED

• Unused imports removed

KNOWN ISSUES

• Zombified Piglins' aggression behaves weirdly, so the bar colour alternates depending on action: Chasing player = isAttacking, anything else = !isAttacking and hasAngerTime - very peculiar behaviour.
• A few mobs, like Hoglins (which are Passive in terms of class), Piglins, and Endermen have unique behaviour that has to be accounted for in manual check

Possible TODOs:

• Fix zombie piglins
• Add more circumstantial text particles, like for critical hits, etc
• Allow very quick configurable LERP on aggression change for the colours.
