feat(fonts): local provider infer

[florian-lefebvre]

Try it with npm i https://pkg.pr.new/astro@976100f

Changes

• New feature!
• When using the local provider, the weight and/or style can be left undefined. In this case, we'll read the font files from src and try infer those properties from there
• Reading those properties uses https://github.com/delucis/fontace from Chris
• Also improves how unicodeRange is handled for empty arrays
