I already have a PR up for slayer health bossbar. Dont want to colllide there :>

[7azeemm]

uh, i'm working on slayer general info like lvl, xp to next lvl, bosses to kill, kill time. this wont hurt your PR for sure :)

Overall changes:

• Added Slayer HUD
• Added Boss slain time
• Added Boss and MiniBoss spawn alert
• Added Mute Enderman sounds
• Tracking all slayer info
• Works with existing slayer stuff

Sorry, but there's a lot going on with the hud and slayers at the time. I'd suggest leaving this until #816 is merged and then I'll look at this.

i made Lazer phase timer for eman slayer
but i messed up with git in intellij
i may have to open new pull request to fix all conflicts and making sure all things work with slayer BossBar and other changes @BigloBot made

• i need help fixing the rendered text being inside entity like this
  RenderHelper.renderText(context, renderText, BossLocation.add(0, 2, 0), true);
