Import known GUIDs for protocols

[rjoleary]

Currently out list only contains file GUIDs: https://github.com/linuxboot/fiano/blob/master/pkg/knownguids/guids.go

Binarly are now maintaining a large list of GUIDs:
https://github.com/binarly-io/guiddb

It is now used in https://github.com/fiedka/fiedka as a submodule.
I suggest doing the same, and autogenerating a Go file based on the JSON, which makes it ultimately portable.

Note: I tried using a file at runtime for PSP file names in #343 and then realized that the underlying file is only accessible in an OS context where there is a file system, so it isn't trivial to bring to GOOS=wasm.
