Bug fixes

• update starts and ends with incorrect data (see #2)
• Incorrect repeats count after reverse (see #3)

API changes

• .convert(cb) - cb now accepts progress as 2nd argument
  1st converter's argument is a value received from previous one.
  Additional 2nd argument lets you get pure progress value
• .use(cb) - cb now accepts options as 2nd argument.
