change_func() method in jobs

[VictorioMaculan]

So, I created this exciting method, job().change_func(), because I think it would be cool to allow the users to change the job's function in a more implicit way, and, it also helps to keep the function metadata. Take a look:

def hello(name):
    print(f'Hello, {name}!')

sch = schedule.every().second.do(hello, 'folks')

while True:
    if timer >= 10:
        sch.change_func(hello, 'friends') # Right here

    schedule.run_pending()

But what do you guys think? Sorry for anything, it's my first time contributing :)
