Built-in hash() method is not deterministic, which breaks cachier since #17

Cachier is broken for me since #17 for string arguments (probably for other built-in objects as well). This comes from the fact that the built-in hash() method is not deterministic between runs in python. Therefore calling it on the arguments of the function for caching purpose does not work between multiple runs because it will hash to different values.

The problematic call to hash() is here.

Repro

Run this script twice in a row and it will re-execute the method test() each time without relying on the cache:

import time
from cachier import cachier

@cachier(pickle_reload=False)
def test(text):
    time.sleep(1)
    print(text)
    print(hash(text))
    return 0

start_time = time.time()
text = 'foo'
print(hash(text))
test(text)
print(time.time() - start_time)

Thanks for fixing this so quickly!

Should be solved by release v1.3.3. Please check and let me know how it goes; you should definitely reopen this issue if this doesn’t fix the issue.
