text: Title: Aroon doc string
  Body: Hi,
  
  First of all thanks for the great lib. 
  I just saw some inconsistency in the doc string of Aroon indicator which can be acessed from link below:
  https://github.com/twopirllc/pandas-ta/blob/main/pandas_ta/trend/aroon.py
  
  The arguments are high, low, length=None etc... But in the help output Args are listed as:
  '
  Args:
      close (pd.Series): Series of 'close's
      length (int): It's period. Default: 14
  '
  
  Maybe I'm missing something but shouldn't the args in the docstring high and low instead of close? 
  
  Best wishes,
