Repeating letter in guess shouldn't match more times than there are instances of the letter in target word.

Example:

$ cabal repl
# [...]
*Main> import Wordle
*Main Wordle> getMatches "brake" "beale" 
# where "brake" is the target word and "beale" is the guess

Expected response:
[('b',InPlace),('e',NotInWord),('a',InPlace),('l',NotInWord),('e',InPlace)]

Actual response:
[('b',InPlace),('e',InWord),('a',InPlace),('l',NotInWord),('e',InPlace)]

The actual response seems to indicate that there's another 'e' in the target word in addition to the one that is in-place, which is obviously incorrect.

Possible fix, match in-place first and then match in-word with the following condition in mind; If the letter is already in-place or in-word and there are no other instances, then mark as not-in-word, else mark as in-word.
