Added linked inputs group

[RunDevelopment]

As mentioned on Discord, I made a group to link the values of inputs. While not perfect, it's functional. The main issue is that values are linked via inputData, so sliders aren't synced in real time, but only when a value is entered (slider is released).

A for the design: it's not done yet. I'll do it tomorrow.

How hard would it be to add a way to define the relationship between the inputs? For example if one needs to be double the other, of if two linked file paths should have a different extension?

Not very. The only hurdle is that you need to be able to describe this relationship in a JSON-API-compatible way. But we don't need this right now, so why add it?

Specifically I'd like to use that for the NCNN load model node, but I guess it's not too big of a deal right now

Huh? NCNN Load Model already syncs up .bin and .param.

Yeah but I've always wanted to replace that with a generic implementation. Right now it's just hardcoded on the frontend
