/**
 * Interpolates different parameters into a string.
 * The provided string can set the parameters to replace wrapping a parameter name in curly
 * braces. This will then be replaced by the parameter value as long as it is defined. If it
 * is not provided, the parameter  name will just be removed from the final string.
 *
 * @param string - The string to interpolate different parameters in.
 * @param parameters - Value of the different parameters to interpolate.
 * @returns The interpolated string.
 * @example Different usages of the interpolate function.
 * ```js
 *  interpolate('https://{env}.empathy.co/{instance}', {
 *    env: 'live',
 *    instance: 'demo'
 *  })     // 'https://live.empathy.co/demo'
 *
 *  interpolate('https://{(api-)env}.empathy.co/{instance}', {
 *    env: 'live',
 *    instance: 'demo'
 *  }) // 'https://api-live.empathy.co/demo'
 *
 *  interpolate('https://api.{env(.)}empathy.co/{instance}', {
 *    env: 'live',
