Short (3 character) hex color codes are converted to black

[Daio-io]

Some SVG optimisers will shorten hex codes for colors like white and black to be a 3 character hex https://svgo.dev/docs/plugins/convertColors/ (It is also possible design teams may export icons with optimised short hex values as well)

The current regex only looks for 6-8 character code hex

private val hexRegex = "^[0-9a-fA-F]{6,8}".toRegex()

Meaning a short character code for white (FFF) will be converted to black

	if(hexRegex.matches(it)) {
	if (it.length > 6) it
	else "FF$it"
	} else {
	"FF000000"
