• Adds the schematic_port and parse the text appropriately.
• Flips the schematic in Y-axis to match the schematic-viewer

@seveibar For the last trace edge to connect to the port, I was debugging but not sure what does the ti in these array mean. If I am not ignoring the ti edge then I am seeing something like this, where the shortest trace is getting added.

@imrishabh18 I'm not sure what ti means (it might be an abbreviation for "... index"), but I think it's out-of-spec so you can probably ignore it.

As for the line, it seems to me like you're drawing the line path such that it's closing itself, the schematic route paths should never self-close. They may need to connect the first/last segment to the x/y of the port, that I'm not sure of. Looking at the spec to see if there's any details...

Yea my guess is if the trace isn't touching the port you basically are supposed to manually connect it by searching for the relevant schematic_port's x/y using from_schematic_port_id or to_schematic_port_id

Fixed the last trace edge issue @seveibar
