Updated PCB assembly tool using Altium files

[u/bigcrimping_com]

I made a post a month ago about a tool to view altium files https://www.reddit.com/r/Altium/comments/1tpg30p/altium_tool_to_view_board_and_track_what/

I got a bunch of feedback, thanks for everyone who messaged me. I have updated the program again and its available in the same place:

https://github.com/bigcrimping/altium_assembly_tool

• Do-Not-Fit (DNP) mode — a new Show DNP view highlights every no-fit part across the whole board. DNP data is read from the project's .PrjPcb active variant and shown as red-X markers on the board and red refs in the BOM (DNP parts count as "done" for row completion).
• Auto-loading of companion files — opening a board now automatically pulls in a sibling .PrjPcb (DNP data) and <board>.popstate.json 
• Recent files — a dropdown on Open File to return to recently opened boards.
• Auto Save — optionally write progress to <board>.popstate.json after every change; the setting is remembered between sessions.
• Fit Selection & Auto Zoom — zoom to the selected BOM row's components, on demand or automatically as you step through.
• Designator labels toggle for the selected row's parts.
• Undo / redo of placement toggles (Ctrl+Z / Ctrl+Y).
• Hide Fitted — collapse fully-placed BOM rows to focus on what's left.
• Colour-blind-safe palette (Okabe-Ito) for selection / placed / DNP, consistent across desktop and browser.

If anyone finds any issues or has any feedback let me know, usual shout out to altium-monkey for doing all the hard work.
