Marcharper patch 1 fix type hints

[drvinceknight]

This fixes the two errors:

axelrod/fingerprint.py:444: error: Function "numpy.array" is not valid as a type
22
axelrod/fingerprint.py:444: note: Perhaps you need "Callable[...]" or a callback protocol?
23
Found 1 error in 1 file (checked 1 source file)

and:

axelrod/strategies/ann.py:125: error: Incompatible types in assignment (expression has type "ndarray", variable has type "List[int]")
34
Found 1 error in 1 file (checked 1 source file)

note that in fingerprint.py I'm using the ArrayType type but that
when I tried to use that in ann.py a lot of other things broke.

This is failing due to numpy 1.20.0 not being yet what we run on the CI so numpy.typing is not available:

The version that gets install (numpy only has a lower bound pin in requirements.txt) is apparently numpy-1.19.5:
