feat(core/write): allow to supply listener for write failures

[sranka]

Fixes #197

Proposed Changes

The following property was added to writeOptions, so it is now possible to know/observe/react upon writing failures in a custom way.

  /*
   * writeFailed is called to inform about write error
   * @param this the instance of the API that failed
   * @param error write error
   * @param lines failed lines
   * @param attempts a number of failed attempts to write the lines
   * @return a Promise to force the API to not retry again and use the promise as a result of the flush operation,
   * void/undefined to continue with default retry mechanism
   */
  writeFailed(
    this: WriteApi,
    error: Error,
    lines: Array<string>,
    attempts: number
  ): Promise<void> | void
