cannot use with `dill`

[weaver9651]

Hello. When I use alive-progress with dill package, an error occurs. Here's the code that I tried.

import time

import dill
from alive_progress import alive_bar

total_len = 1000
with alive_bar(total_len) as bar:
    for _ in range(0, total_len):
        time.sleep(0.001)
        bar()

Please let me know if I missed something. Thank you.

Oh boy, dill's author has used a protected logging class, which is Python's last resort internal processing... 🤦‍♂️

But ok, I think I can ignore errors in there...

Release 3.0.1 fixes this.
