  interface BabelPluginEnumToObjectOptions {
  /**

   * }
   * reflect: true
   * =>
   * const Status = {
   * PAID: 0,

before add plugin：

enum Status {
  PAID,
  UN_PAID
}

// =>

var Status;
(function (Status) {
  Status[Status.PAID = 0] = 'PAID'
  Status[Status.UN_PAID = 1] = 'UN_PAID'
})(Status || (Status = {}))

after add plugin：

enum Status {
  PAID,
  UN_PAID
}

// =>
// default (reflect is true)
const Status = {
  PAID: 0,
  0: 'PAID',
  UN_PAID: 1,
  1: 'UN_PAID'
}
//  set reflect false
const Status = {
  PAID: 0,
  UN_PAID: 1,
}
