Example:
// Create instance - better call only once because of the performance bottleneck
svg := goimgsvg.NewGoImgSVG()
// Print an svg based on svg filename in the folder ./assets/goimgsvg/svg/
flag := svg.GetSVGByFilename("eur")
// Print all .tld-svg related supplied currency tru translation in the folder ./assets/goimgsvg/tld_cur.tsv
flag := svg.GetSVGByCurrency("eur")
