Support for char fields

[apenlor]

Both char or char[] fields are causing failures during the compilation.

For char
java: incompatible types: java.lang.String cannot be converted to char

For char[]
java: java.lang.NullPointerException: Cannot invoke "Object.toString()" because "o" is null

CharType does not exist in Pact, so I change to be a StringType

  @Example("a")
  private char aChar1;

  private char aChar2;

Code generated

          String aChar1 = "a";

          String aChar2 = "g";
;

      public DemoClassBuilder setAChar1(final String aChar1) {
    this.aChar1 = aChar1;
    return this;
  }
      public DemoClassBuilder setAChar2(final String aChar2) {
    this.aChar2 = aChar2;
    return this;
  }

    public DslPart build() {
        PactDslJsonBody pactDslJsonBody = new PactDslJsonBody();
      if (Objects.nonNull(aChar1)) {
          pactDslJsonBody.stringType("aChar1", aChar1);
      }
      if (Objects.nonNull(aChar2)) {
          pactDslJsonBody.stringType("aChar2", aChar2);
      }

        return pactDslJsonBody;
    }

Support for char[] is still pending

java: java.lang.NullPointerException: Cannot invoke "Object.toString()" because "o" is null

@apenlor the problem you reported happens in every type of Array
It should be treat as a new issue in my point of view

Makes sense :)
