Support weight prefixed local fonts

[jbebe]

Right now a very quirky-looking method checks the filename and extracts the weight value.
Instead, I suggest the much simpler weight number prefix at the end of the filename, like "Arial-200.ttf" where 200 is extracted as the weight. I think it's more common than the "Arial-extralight.ttf" variant.

But the easiest approach would be to just simply delegate the weight extraction to the user by adding a callback to the config like this:

VitePluginFonts({
      custom: {
        getWeight: (x) => {....},
        families: [ ... ]

We accept PRs 🙂

I'm aware of that, thanks for mentioning.

This will be available on next release #39

Unfonts({
  custom: {
    display: 'swap',
    families: {
      'Dancing Script': {
        src: './assets/fonts/DancingScript*',
        transform(font) {
          if (font.basename === 'DancingScript-Bold') {
            font.weight = 700
          }

          return font
        },
      },
    },
  },
})

where font has a type like:

export interface CustomFontFace {
  source: string
  name: string
  basename: string
  weight: number
  style: string
  display: string
  local?: string | string[]
  files: {
    src: string
    ext: string
    path: string
    format: string
  }[]
}

you can override any values or return null to exclude the font!
