combinatorics.combinations() added

New features

• combinatorics
  • combinations()
  • combinationsAsync()
• Stream
  • combinations()

Stream and AsyncStream made generics to save the typing

Improvements

• Stream and AsyncStream are fully refactored
  • Classes made generic.
  • All the methods made generic and save the typing.
• reduce
  • toValue(), toValueAsync() — union return type has been replaced by inferred type.
  • toRange(), toRangeAsync() — use Numeric type in arguments.
• multi
  • Type ZipTuple — added support for iterators and async iterables / iterators.
• math
  • All the methods use Numeric type in arguments.
• All the tests are refactored to check the typing.
• Found bugs fixed.

New features

• types
  • Numeric
  • NumericString

Union return type in groupBy replaced by inferred type

Improvements

• single
  • groupBy() — union return type has been replaced by inferred type.
  • groupByAsync() — union return type has been replaced by inferred type.
