**Undocumented:** Gets a logged-in user's capes for a given profile.

**I have no idea what this endpoint returns!** I just saw the official website try to use it.

@param {Object} session - object from authentication
@param {string} session.accessToken - valid access token for the user's account
@param {string} profileId - game profile UUID to look for capes in
@returns {Promise<Array>} resolves with an array of something
function getUserCapeData ({accessToken}, profileId) {
  return fetch(`${CORE_API}/user/profile/${profileId}/cape`, {
    headers: {
      'user-agent': USER_AGENT,
      'authorization': `Bearer ${accessToken}`,
      'accept': 'application/json'
    }
  })
    .then(handleErrors)
    .then(res => res.json())
}
