[FTR] Pattern "Repeated"

[romshark]

Proposal

Introduce a new pattern Repeated to allow grammars to specify a repetitive sequence of a particular pattern with a minimum and a maximum number of repetitions:

Repeated {
  Min:     1,
  Max:     10,
  Pattern: Exact{Expectation: []rune(".")}
}

• Max: 1 and Max: 1 should be considered illegal.
• Min > Max should also be considered illegal.
• Max: 0 should be equal to unlimited.

This pattern should replace ZeroOrMore and OneOrMore.
