Length matching across layers feature

[Victor W]

One of the most time consuming tasks we face is length matching nets and net groups. We need to length match across layers, and to different target skews.

What we are looking for is a mechanism to specify all the target lengths for various nets in one location or dialog box, and, critically, have Kicad calculate the total net length while taking into account the stack up dimensions and layer height.

There are three elements to this request then;

1) A dialog box where we can specify the target length for specific nets

2) A location where we can specify stack up geometry (related to https://bugs.launchpad.net/kicad/+bug/1783135)

3) Update the length matching calculator to account for the stack up when calculating target lengths.

Right now, we have to do all the length matching in a spread sheet, making later modifications very fragile and error prone. Our boards are fairly complex, with a substantial amount of length matching; this feature would save us considerable work.
