text: Title: Dev Branch: Chandelier Exit offset direction
  Body: **Which version are you running? The lastest version is on Github. Pip is for major releases.**
  I am using python 3.9 and pandas_ta 0.4.19b0 (dev branch).
  
  **Do you have TA Lib also installed in your environment?**
  no
  
  There is a bug in the development branch of the volatility indicator "Chandelier Exit", see here:
  https://github.com/twopirllc/pandas-ta/blob/438f3a97b71b26bc17efb1a204fb0e0fdc48e0aa/pandas_ta/volatility/chandelier_exit.py#L108
  
  ```python
      direction = uptrend + downtrend
      if direction.iloc[0] == 0:
          direction.iloc[0] = 1
      direction = direction.replace(0, nan).ffill()
  
      # Offset
      if offset != 0:
          long = long.shift(offset)
          short = short.shift(offset)
          direction = short.shift(offset)
  ```
  
  If you add a nonzero offset, the direction column is replaced with the shifted short column. In reality you would want the direction column to be shifted itself.
  Here is what I believe to be the corrected version (only the last line is changed):
  
  ```python
      direction = uptrend + downtrend
      if direction.iloc[0] == 0:
          direction.iloc[0] = 1
      direction = direction.replace(0, nan).ffill()
  
      # Offset
      if offset != 0:
          long = long.shift(offset)
          short = short.shift(offset)
          direction = direction.shift(offset)
  ```
