v1.10.0

• Added new entropy_maximum method to calculate theoretical maximum entropy
  for a text given an alphabet size
• Made size parameter required in entropy_ratio and entropy_ratio_minimum
  methods instead of defaulting to text.size
• Updated YARD documentation to clarify that size parameter represents
  alphabet size
• Modified examples to use explicit alphabet sizes for better clarity
• All entropy methods now consistently return values in bits as expected for
  Shannon entropy
• Updated documentation examples to use simplified method calls without
  MoreMath::Entropy prefix
• Enhanced entropy_maximum method documentation to explain its use in
  determining security strength for tokens
• Added comprehensive tests for entropy_maximum function covering edge cases
  and various alphabet sizes
• Improved entropy_maximum method signature to return 0 for invalid
  alphabet sizes (≤ 1) and use Math.log2 for calculation
• Updated existing entropy method documentation to clarify it calculates
  entropy in bits
• Simplified example code in documentation to use direct method calls instead
  of module prefixes
