To me, it made more sense to track which boards go together in a cluster;
when reviewing a request to actually use a duplicate vid/pid, you want
to know what board(s) it is aliasing.
I also revamped the detection of non-USB boards so that a board .mk file
that couldn't be parsed by the code here would raise a problem instead
of just being skipped for the purposes of checking.
There were some lines with comments on the end, and some variation in
capitalization of the IDs. These are all normalized and a (sometimes
unfriendly!) error printed when it's incorrect.
Before this, here were some ways to trick the duplicate vid/pid checker:
```
USB_PID = 0XABCD
USB_PID = 0xAbCd
USB_PID = 0xABCD # harmless comment?
```
None of these things were ever done on purpose.
@dhalbert noticed that if a fork was called `micropython`, the
existing check could fail during CI because it will be cloned into a
directory also called `micropython`.
Instead of hardcoding a range of strings that are OK as top directories,
find the location of the top directory relative to the script.
This will be conflicty after #5069 is merged, but it should be easy to
fix.
.. this board is nearly the same as the "1.2" version originally
released, but makes a few changes to reduce pin conflicts between the 13-pin
camera header and the bootstrapping pins. "1.3" was introduced in summer
2020-- check the bottom of your board silk to find out whether you have a 1.2
or a 1.3, because it's not clear whether there is remaining 1.2 stock.
Another vexing fact about the 1.3 is that its LCD can have one of two
chipets, and the chipset used is not marked anywhere!
