Fix black SVG elements

[adamdebono]

Added explicit fill="#000" to SVG elements which should be black.

So far have completed ISO codes beginning from a - e.

Fixes #1123

Awesome!! I can see that is still a draft.. so I'll wait until you tell me.

I figured it would be easier to gradually do them all in this one PR, otherwise it might be hard to keep track of what's been done.

If you're happy with this then I'll keep adding to this until all of them are updated.

[lipis]

Sure thing! Keep going.. thanks a lot!

@lipis I've gone through them all now, I don't think I missed anything.

[lipis]

Awesome!! Thank you very much.. I'll check it and merge tomorrow!

It seems that SVGO is removing this value because it's the default: gregberge/svgr#380

Hmm.. one way is to disable it is to add the removeUnknownsAndDefaults https://svgo.dev/docs/plugins/remove-unknowns-and-defaults/

Will experiment :)

[lipis]

It doesn't seem to work :/ and it keeps removing the fill="#000".. maybe I'll change it #000001
