Move to own parser

[orangain]

Now json-fuzzy-match does not depend on Karate. I will update README in later PR. There are some breaking changes.

Breaking changes

• Lenient JSON syntax is no longer supported. Both pattern and actual value must be a valid JSON string.
• The following complex matchers are no longer supported.
  • Optional fields, e.g. ##number
  • #? EXPR: self-validation expressions
  • #(EXPR): embedded expressions
  • Using expression in advanced array validation, e.g. #[]? _.length == 3
• Now #uuid marker requires just 36 characters.
• Error message in AssertionError has slightly changed.
