Adding functions to video.py - getting "AttributeError: 'ApiWrapper' object has no attribute '<new function name>'"

[dbrandesky]

I'm attempting to contribute to this project by adding some API options I'd like to use for my Amcrest IP5M cameras. I figured out the "pattern" for the functions in video.py; the particular item I'm adding is a "video in" option, so I created the following in the corresponding section of video.py:

   def set_night_switch_mode(self, value: int, channel: int) -> str:
        # 0: No Switch, always use day
        # 1: Switch depends on brightness
        # 2: Switch depends on time, switch to Night when time is after sunset or before sunrise
        # 3: No Switch, always use Night
        # 4: No switch, always use Normal
        return self.set_video_in_option(
            "SwitchMode", str(value), channel=channel
        )

    async def async_set_night_switch_mode(self, value: int, channel: int) -> str:
        # 0: No Switch, always use day
        # 1: Switch depends on brightness
        # 2: Switch depends on time, switch to Night when time is after sunset or before sunrise
        # 3: No Switch, always use Night
        # 4: No switch, always use Normal
        return await self.async_set_video_in_option(
            "SwitchMode", str(value), channel=channel
        )

I then created a venv to test my changes, made sure all the requirements were installed, then followed the instructions in the README to run some commands in a Python CLI.

First I ran the example in the README with no problem:

    from amcrest import AmcrestCamera
    camera = AmcrestCamera('192.168.0.1', 80, 'admin', 'password').camera

    #Check software information
    camera.software_information
    'version=2.420.AC00.15.R\r\nBuildDate=2016-09-08'

I then tried running my new function and received the following feedback:

camera.set_night_switch_mode()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'ApiWrapper' object has no attribute 'set_night_switch_mode'

I'm not really sure how I can update the ApiWrapper, from what I can tell it just calls each class so it should import the new functions as well. I know a decent amount about Python scripting but I'm far from a developer so I could be missing something obvious.
