ENH: Optional Timezone

[Miksus]

This PR implements custom timezones and custom time measurement function (for testing).

Set the timezone:

from rocketry import Rocketry
import pytz

app = Rocketry(timezone=pytz.timezone("Europe/Helsinki"))

Set the time:

def fix_time(dt):
    "Get new time measurement function"
    start_time = time.time()
    def get_time():
        sec_since_start = time.time() - start_time
        return dt.timestamp() + sec_since_start
    return get_time

app = Rocketry(fime_func=fix_time("2014-04-31 10:00:00"))

Other changes:

• Start, end and runtime are passed as epoch to task log repos
• last_run, last_success etc. are not in the JSON representation of a task anymore due to limitations in Pydantic.

Further Idea

Perhaps in the future we could have something like:

with app.test_time("2022-04-31 10:00:00"):
    app.start()

Not sure.
