Darknet shortcut support for new fork

[HagegeR]

Hi @lutzroeder ,

I think that the from parameter is not implemented correctly.

A correct implementation is detailed here : AlexeyAB/darknet#4662

I'm not sure that #335 is completely correct: from what I understand by the code, only [scale_channel] implement partially the from attribute, [shortcut] and [sam] layer should implement it too.

thanks for your help lately with the darknet implementation!

@HagegeR, can you create a fix and submit a PR.

@lutzroeder I'm not sure how to do it really, how do you get multiple inputs in there:

netron/src/darknet.js

Line 204 in a2c18fc

let index = option_find_int(options, 'from', 0);

@HagegeR, check a few lines down for const routes.

So, basically, I tried that:
https://github.com/HagegeR/netron/blob/42fd3dab464e1326f20d23c2567a992ad6d99171/src/darknet.js#L204-L223
