[OneExplorer] Support viewer for tflite/onnx

[dayo09]

What?

Let's support viewer for tflite/onnx.
Logically, netron support boths, but it seems that the current circle-dedicated viewer (CircleViewer) is not working with tflite/onnx files.

The error message showed up when I tried to open a tflite file with circle viewer.

@seanshpark AFAIK, the circle-netron supports tflite/onnx files. However, it seems that our CircleViewer doesn't support them. Do you think that it's possible to support tflite/onnx files, too?

Current implementation: NO

How netron supports multiple formats?

• it dynamically loads file loader .js files

How current circle viewer control works?

• static loading of circle file loader codes and some fixed codes based on handing circle files
• has some modification for partition editing that may disturb loading tflite/onnx

So, IMHO, how to support tflite/onnx files?

• for simplicity, add another module for tflite and onnx both or two modules for each

Oh, therefore we need to port other modules to support tflite/onnx viewers... :-D
