Revisit video streaming code

[tame0001]

Last semester we did streaming video. It has been a while, so it is time to brush up the code.

• Create a new package for video streaming sending side. Choose the name that tell its functionality.
• Clean up the code here a little bit -> https://github.com/boilerrobotics/rover-code/blob/master/src/cv_basics/cv_basics/publisher.py
• You should put any additional dependencies in package.xml with rosdep. See the end of this README -> https://github.com/boilerrobotics/rover-code/blob/master/README.md
• Create a subscriber package in base_station repo -> https://github.com/boilerrobotics/base-station. Follow the same step as above

I created a package for base station -> https://github.com/boilerrobotics/base-station/tree/main/src/remote_operation. This is for the receiving side. See package.xml about dependencies. The code is not ready, so we will need to work on it.
You will need to create a new package for the sending side in rover-code repo. You can see example for package.xml.
I also found more example for using cv_bridge
