Feature request: Make styles customizable

[rudolfbyker]

The defaults for export const STYLE in constants.js are not very pretty, even for DX. I would like to modify it if possible. Until then, I'm using a patched version of vue-axe. ;)

I will add this customization in v3 too.
Thank you for that.

Thanks for the suggestion.
