Release 10.6

• (configurable) StackOverflowError protection against deeply nested recursive structure. Makes dot-parse the safest Java recursive descent parser.

• extensive benchmarks stacking dot-parse against major Java, Scala and Kotlin parser frameworks.

• digits(n), hexDigits(n) parsers. Easier to express regex-like composite patterns like:

  Parser<String> usPhoneNumber =
      sequence(digits(3), one('-'), digits(3), one('-), digits(4)).source();
  

• Parser.mapWithIndex() makes the source index usable by the grammar.

• Parser.OrEmpty.source() and Parser.OrEmpty.map() makes optional parsers more convenient.

• bug fixes.
