text: Title: Good First Issue >> Strictly Increasing / Decreasing
  Body: Thanks for Pandas-Ta
  Can you add a "strictly" boolean parameter to the Increasing / Decreasing function?
  Now you are checking the difference between the current value with a length value ie. increasing = close.diff(length) > 0
  But I want to check continuous increasing / decreasing condition like 
  ```python
  test_list = [1, 4, 5, 7, 8, 10] 
  res = all(i < j for i, j in zip(test_list, test_list[1:])) 
  which result True
  
  test_list = [1, 8, 5, 4, 8, 10] 
  result = False
  ```
