PCB Updates

[qwertymodo]

After building a set of these by hand, I ran into a handful of difficulties and wanted to make some tweaks to the PCB to address them. The main changes made here are:

1. Replace 0402 passives with 0603 to improve ease of assembly, and the crystal oscillator with a much lower profile 3225 package to avoid clearance issues with the HC49 can height.

2. Remove mouse bite tabs with cleanly routed edge cuts, and instead use V-scoring for rail removal.

3. Fix most DRC errors and warnings

I haven't bothered to fix up the reference designators on the silkscreen layer, because it didn't seem like you used them, but if you would like that done as well, let me know and I can do that as well.

Please do look over both the schematic and PCB before accepting this PR, I'm still quite new at KiCad, so it's entirely possible I might have broken something. Also, note that I used KiCad 7.0 in my editing, so the files have been updated to require that version.

Hey, thanks for the PR and sorry that I have not responded yet. At the moment I do not have much time to look into the details, but I am sure that I'll be learning a thing or two from it.

But before merging I need to decide if I will add it as a variant next to the original one, because it will probably break the BOM and the pick and place data for the assembly service and I doubt that many beginners will be prepared to build them by hand. But then again, in practice, that process is probably broken anyway due to unavailable parts (haven't checked in a while) and most beginners will simply by an assembled Interceptor from Aliexpress anyway.

Well, I will try to look into it soon :)

Yeah, this will definitely need the BOM and PnP data updated. I swapped out components, and also moved them around a little bit. I don't believe I made any real changes to the schematic, other than the version update and other minor design sync updates.
No worries on the response time, I probably won't be building any more of these (maybe I'll do one more batch to test out these updates), just wanted to contribute back based on my experience building a few.
