Allow body schema when type is multipart

Line 240 in 9fa16b6

assert(/json|form/.test(spec.validate.type), text);

It throws error when I use type: 'multipart' with body schema.

Should it be allowed to parse multipart/form like below?

form.append('name', 'name');
form.append('image', image); // jpeg image

axios.post(url, form, { headers: { 'Content-type': 'multipart/form-data' });
