The first fread call fills our 32 KiB buffer, and then we enter a busy

Upstream edid-decode hides the serial number in this case.
The spec says that it's optional, and set to zero when unused.

While this isn't particularly interesting to print, this reduces
the diff between di-edid-decode and edid-decode.
This is not exposed via the low-level EDID library because callers
wouldn't have a use for it.

This utility displays low-level EDID information. It uses the same
format as the official edid-decode CLI tool from linuxtv.org. It
will be helpful for testing.
