Add text/values to parts (especially skinned) about netlistsvg

[amstan]

I'm really sorry, this looks to be handled by #38

[amstan]

Nevermind.

I saw this picture and got excited, but we don't do that yet:

We would need to edit the default skin file to have those attributes for the resistors and other parts.

Yeah, ideally each cell template should be able to add as many text boxes as it likes and indicate which attributes from the netlist cell to pull them from. I think that's where we were going with #35?

[nturley]

ah, I see what happened here. It was completed but never added to the analog skin. I'll add them back.

In addition to just adding the labels to the skin, there's some additional work to getting the labels into ELK so that layout routes around them.

Looks good so far! Thanks!
