Subclass the PyTorchYolo and PyTorchDetectionTransformer estimators off the PyTorchObjectDetector estimator class

[f4str]

Is your feature request related to a problem? Please describe.
There is a lot of code overlap between the PyTorchYolo, PyTorchDetectionTransformer, and PyTorchObjectDetector estimators. This causes bugs to have to be fixed in both locations when reported. Missed changes in one estimator will still remain a bug in the other. In additional, the big overlap in code is redundant and makes it tedious from a maintenance perspective.

Describe the solution you'd like
The PyTorchYolo estimator should be subclassed off PyTorchObjectDetector. This will reuse a lot of the code and avoid redundant bugs.

Describe alternatives you've considered
N/A

Additional context
This is purely an codebase housekeeping change. Functionality should not be changed in any way.

Hi @f4str Thank you for opening this feature proposal. I think this is great idea. I have combined the two issues to see both changes in the same PR.
