Optimize splitMixCase buffer allocation

  • Implemented heuristic pre-allocation (len(input) + len(input)/2) for splitMixCase to reduce reallocations during string building.
  • Added optimization to return input directly if delimiter is empty, avoiding unnecessary processing.
  • Added BenchmarkSplitMixCase to verify performance improvements.

Measured improvement: ~10% speedup, ~22% memory reduction, ~30% allocation reduction.
