2001.1.0 Release

[icolwell-as]

Resolves #27 by Releasing the first ROS2 version of this driver.

This 2001.1.0 version will coincide with an updated 1.1.0 release of the ROS1 driver.

Tested with GigE Mako G-319. Works as expected.
Hoping @Souphis has time on Monday to test on the USB camera to confirm it works.

@icolwell-as So, I managed to run USB cameras with this version. However, there are some problems with the parameter server. Some float parameters cannot be set after reading them from cameras. For example, the gain range is (0.0, 8.0), the current cameras gain is 2.6, and then the driver gives an error that, the value is out of the range. The same happens with exposure_time, etc, the problem doesn't exist with auto mode enabled.
Also, I think there should be a service for stopping and starting cameras. To set the purpose of the GPIO you have to choose the line and then set the feature value. When doing this during runtime, the driver freezes.

Thanks for testing @Souphis! I can't seem to reproduce your gain/exposure parameters issues with my camera. I suggest creating a new issue and describing the steps you followed to reproduce the issues/errors.
Regarding the service for starting/stopping the camera, each time a parameter is updated, the camera stream is stopped and started again, see here. Is this not working quite right for you?

Anyway, since we are in a bit of a time crunch, and this version mostly works, I'm going to go ahead and release this version, then we can work on updates to resolve your issues for a future release.

Thanks again for testing and confirming it works!

@icolwell-as ok, so release it. If you don't mind I can try to rewrite it to life cycle node (this will resolve the need for start/stop). And about this parameter error, I will try to reproduce this today or in the proceeding days.

@Souphis certainly! happy to take any PR you think is an improvement into consideration! lifecycle is probably the best way to handle the parameter changes.
