Some files are missing viewBox

[kgridou]

Hi @HatScripts,

I am using your svgs to create a lib to be used in angular apps.

I noted that some files are missing viewBox and can't be resized with css, exactly what described here:
#7

For example it-42: https://github.com/HatScripts/circle-flags/blob/98574d233dd251130dbe8ebc73468f0a5568ace4/flags/it-42.svg?short_path=60b2404

Thanks
