SRP&WIZ mixins

First release.

Optional native fixes for Scape and Run: Parasites 1.10.7, split out of my content mod Insane Tweaks SRP&Wizardry so any SRP pack can use them without shipping a content mod. Mixin-only: no items, no blocks, no entities.

Everything is off by default. Freshly installed, this mod does nothing. Turn on what you need in config/srpwizmixins.cfg; no option needs a restart.

What is in the box:

• Cap-purge protection — stop SRP's over-population cull deleting Beckons and Nexuses, or any parasite standing near a player. Two configurable radii.
• Starting points fix — make SRP's per-dimension dimension;phase;points setting actually stick, instead of silently falling back to the global default.
• Save-data thread safety — two fixes for running SRP alongside EntityThreading, covering both point writes and the moment SRP's save data is first created. Required if you have parasites unlocked in more than one dimension while a threading mod is active.
• Per-dimension mob caps — give listed dimensions their own multiplier instead of sharing one global parasite cap.
• Infestation spread throttle — divide both the speed and the tick cost of block infestation. The creep still spreads, it just takes longer.
• Point-update fast path — skip the bookkeeping SRP does for point updates it was going to reject anyway. Identical behaviour, less CPU.
• Diagnostics — optional logging for what removed a Beckon or Nexus, and how each dimension's points were set up at world load.

If you are updating from Insane Tweaks 1.2.0 and had srpCompat toggles enabled, re-set them here — they no longer exist in insanetweaks.cfg.
