Allow using new ArrayBuffer(0) in withRequest.body to be honest in the contract tests

[canny]

Our Team Lead proposed exciting things when we tried to cover our API endpoint (.NET language) with a contract test, which required binary content in the request body. But, as Matt Fellows mentioned, we cannot interpret new ArrayBuffer(0) in something at JSON.
So, my question is - can we allow engineers to use new ArrayBuffer(0) in withRequest.body, but with interpretation to something like empty JavaScript object ( {} ) or something "magic" actions. In any case, this allowed us to write more honest contract tests, with explicit marks, that we expected to use in the request body - new ArrayBuffer(0) and can verify that in the generated pact specification.
