v1.11.0

• Added new entropy helper methods: entropy_probabilities,
  entropy_per_symbol, minimum_entropy_per_symbol,
  collision_entropy_per_symbol, entropy_total, minimum_entropy_total, and
  collision_entropy_total to lib/more_math/entropy.rb
• Replaced the old entropy method with an alias to entropy_per_symbol
• Updated documentation for entropy_ratio to clarify the size: keyword
  argument
• Removed the entropy_ratio_minimum method and its corresponding test cases
  from the codebase
• Enhanced test coverage in tests/entropy_test.rb with new unit tests for the
  added helper methods
  • Updated existing test assertions to use assert_in_delta for
    floating-point comparisons
  • Added descriptive comments to the test setup method
  • Ensured all new methods return correct values for empty, uniform, and
    varied symbol strings
• Corrected example values in entropy_ratio documentation
