spaces in key raise Non-base32 digit found

[bytescreator]

it's not a real issue but users can call functions with separated keys.

$ echo "ZYTY YE5F OAGW 5ML7 LRWU L4WT ZLNJ AMZS" | python3 mintotp.py
Traceback (most recent call last):
File "mintotp.py", line 30, in

return hotp(key, int(time.time() / time_step), digits, digest)
File "mintotp.py", line 11, in hotp
key = base64.b32decode(key.upper() + '=' * ((8 - len(key)) % 8))

you were right at the first two issues i was using python2.7 sorry for that.
Spaces in the keys broke the script it's not a real issue but i think it's worth to know

key = base64.b32decode(key.upper().replace(" ","") + '=' * ((8 - len(key) + key.count(" ")) % 8))

There is no plan to support spaces in the key.
