Generate .dfu files

[Ralim]

Adding in dfu files that have the dfu suffix

Will drop bin files once these are known to work.

Fixes #1050

@tormodvolden
Can you give this a look over

[tormodvolden]

Debian/Ubuntu ships dfuse-pack but doesn't install it in the path (yet?), you can pick it from /usr/share/doc/dfu-util/examples/dfuse-pack.py.gz (and uncompress).

[tormodvolden]

On the other hand their current version is so old you're better off picking it from upstream like you did :) Did you pretty-format the script?

[Ralim]

Haha, honestly didnt dig much except to find it wasnt in path; shrugged and pulled it in. I did format it as habit though (by virtue of opening it once in vscode and hitting save as habit).
Also if its not in ubuntu main package feels a bit weird to have to extract it from an odd path, as thats going to confuse any non-ubuntu uses out there (like me) 😂

[tormodvolden]

I'll pick up the reformatting upstream, with your authorship, if that's fine with you.

I have a dfu-util 0.11 including dfuse-pack.py in my PPA, using the package source "deb http://ppa.launchpad.net/tormodvolden/ppa/ubuntu trusty main" (also works on focal) if that could be an alternative.

[Ralim]

Oh the reformatting is done by tooling so I don't really need credit tbqh.

Do you expect the PPA to be around for the long term 😂 (Well at least until ubuntu puts it as part of the main package?)

If so, happy to swap to it

[tormodvolden]

Yes, the PPA has been around for ages and touch wood it will.

[Ralim]

Eugh the PPA requires a chunk more work to load in as need to either pull in keys or install the ppa helper I believe (which increase image size and runtime of CI) 😢

[Ralim]

@tormodvolden
If there is a simple way to use the PPA without pulling in more dependencies I will change to it :)
But merging this for now as its better than before

[tormodvolden]

Instead of using the ppa helper, you can import the PPA key with this, probably without new dependencies:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4B1E287796DD5C9A
