[AlexCatarino]

Description

The second and third parameters are fastPeriod and slowPeriod, but we had slowPeriod and fastPeriod, which is inconsistent with the class constructor and other indicators with fastPeriod and slowPeriod parameters.

Motivation and Context

Consistency and documentation.

Other platforms follow this conversion:

• https://technical-analysis-library-in-python.readthedocs.io/en/latest/ta.html
  short and long, which is fast and slow respectively

ta.momentum.AwesomeOscillatorIndicator(high: pandas.core.series.Series, low: pandas.core.series.Series, window1: int = 5, window2: int = 34, fillna: bool = False)

https://qtpylib.io/docs/latest/indicators.html#awesome-oscillator

bars['ao'] = bars.awesome_oscillator(weighted=False, fast=5, slow=34])

AO(fast_period: int, slow_period: int, ...)

Requires Documentation Change
