Allow Binary as a POST body type

[diquah]

Is your feature request related to a problem?

Currently, to send binary data I have to create and pick a file. However, my application uses many small binary packets in place of JSON. In order to simulate these requests I would have to make a file for every type of POST request.

Describe the solution you'd like

It would be really neat to have a "binary" type where hexadecimal or base-64 encoded binary could be submitted into the input box for the body, which would then be converted into a raw byte array for transit.

Inputting binary in hex form would look like this: 83 A3 69 6E 74 01 A5 66 6C 6F 61 74 CB 3F E0 00 00 00 00 00 00 A7 62 6F 6F 6C 65 61 6E C3

And Base64 like this: gqVoZWxsb6V3b3JsZKRib29sww==

Inputting binary data would have be in a text form because it needs to be represented somehow, but having to save a file for each message really disrupts from the flow of having everything in the editor.

I've added Binary Base64 body type. Hex support wasn't added because it's less common and easily converted to Base64.
