Add PyCUDA object detection class to be used instead of PyTorch

[Tiryoh]

What does this implement/fix?

https://github.com/rt-net/jnm_jupyternotebook/issues/11 の不具合を回避するためにPyTorchの代わりにPyCUDAを使ったNotebookに入れ替えます。Notebookの挙動は物体検出のみとなり障害物回避はしなくなるため若干異なります。

Does this close any currently open issues?

11 が関連issueです。

How has this been tested?

jnmouse_jp451_v2.zip をJetson Nano Mouse実機にインストールして動作確認
