[feature request] add option for two spaces before alignment character

[gilbertohasnofb]

I would like to use this package to align comments in Python. If I set Align By to # and Alignment Space Chars to #, I can modify the code below:

word = 'apple'
print('a' in word)  # True
print('pp' in word)  # True
print('' in word)  # True
print('x' in word)  # False
print('z' not in word)  # True
print('a' not in word)  # False

into:

word = 'apple'
print('a' in word)     # True
print('pp' in word)    # True
print('' in word)      # True
print('x' in word)     # False
print('z' not in word) # True
print('a' not in word) # False

This already looks really good, but the thing is that PEP8 recommends that there should be at least two spaces between a statement and an in-line comment. But using this package as I describe will always add a single space between statement and comment token. Would it be possible to add the option Add Two Spaces Prefix or something like this to this package?
