Fix/refactor videomode folder

[TheoLaudatQM]

Rename the module called video_mode into live_mode to avoid confusion with the video mode tool used to tune up quantum dots devices.
We can still debate on the name if you think that another one would be more relevant for this tool which is used for updating parameters from a QUA program while the program is running in an asynchronous manner.

What about if we have the video_mode/__init__.py import the original functions/classes which are now in live_mode? This way the code remains backwards compatible

[TheoLaudatQM]

@nulinspiratie What I had in mind was this

import warnings
warnings.warn("the video_mode module is deprecated, please import live_mode instead", DeprecationWarning,
              stacklevel=0)
from qualang_tools.live_mode.livemode import LiveMode, ParameterTable

__all__ = ["LiveMode", "ParameterTable"]

But

1. the warning doesn't show up when calling from qualang_tools.video_mode import *
2. The user will still get error when running his previous scripts that most likely use from qualang_tools.video_mode import VideoMode, ParameterTable

@TheoLaudatQM looks like a nice solution! All good from my end

But

1. the warning doesn't show up when calling `from qualang_tools.video_mode import *`

2. The user will still get error when running his previous scripts that most likely use `from qualang_tools.video_mode import VideoMode, ParameterTable`

1. I am 99% it is possible to display a warning in this case, I can take a look if you want.
2. This can be solved by doing: from qualang_tools.live_mode.livemode import LiveMode as VideoMode.

We can merge if we're okay with the breaking changes and the lack of backward compatibility. Otherwise, we can make it compatible.

[nulinspiratie]

Hmm, if we want to maintain backwards compatibility, we could also opt for the following:

video_mode/videomode.py

from qualang_tools.live_mode import LiveMode
import warnings


class VideoMode(LiveMode):
    def __init__(self, qm: QuantumMachine, parameters: Union[Dict, ParameterTable]):
        warnings.warn("the video_mode module is deprecated, please import live_mode instead", DeprecationWarning,
              stacklevel=0)
        super().__init__(self, qm, parameters)

We would then need to rename the new VideoMode to something else, maybe VideoMode2D?
