Allow ExtendedSize to be shown in utk JSON

[AkechiShiro]

Pull request, allowing ExtendedSize for UEFI to be shown in the JSON output.

This helps to fix this issue fiedka/fiedka#76 but could be useful for others tools as well.

Yea, that's it! Could you please rephrase or just remove the comment? Fiano can be used in other tools as well, so it shouldn't suggest any tight coupling. Maybe include something in the commit message rather, along the lines of "This allows for use with other tools".

Thank you! :-)

Ah, and finally, run gofmt, the Go formatting tool; its code style is very opinionated, and that's what causes the checks to error. 😅

Thanks for your input on this and help, should I also fix some regression tests which are currently failing due to my change?

[orangecms]

So the failing test is the extract+reassemble test pkg/visitors/extract_test.go.

In a first step, I am improving the output. Insead of printing the entire buffer, I print the position and the respective byte, #382

[orangecms]

I gave it another try in #383 by just marshalling the plain Size instead, WDYT?

[AkechiShiro]

If we can get to fix the tests using #383, I'm all down for it, but @GanShun should also give us his thoughts on it, I guess if that changes would be alright in the codebase.
