The wildcard pattern ?* should be treated the same way as *?

[melsabagh]

In Lexpy, ? means "zero or one character" and * means "zero or more characters". Based on this, why is the pattern ?* considered illegal while *? is allowed? Don't they both have the same semantics here:

*?: zero or more || zero or one -> zero || zero, zero || one, more || zero, more || one -> zero, one, more -> zero or more
?*: zero or one || zero or more -> zero || zero, zero || more, one || zero, one || more -> zero, more, one -> zero or more

The code at _utils.py#L15 already translates *? to *, why isn't this also done for ?*?

lexpy/lexpy/_utils.py

Line 51 in b69e029

result = re.sub('(\*\?)+', '*', result) # Replace consecutive '*?' with a single group '*'

This is fixed in lexpy=1.0.0

pip install lexpy==1.0.0

Please test it and let me know if you have any questions.
