🔖 zvariant_utils 3.0.1

• ⚡️ Switch from nom to winnow for signature parsing. This brings in 2 benefits:
  • The signature parsing code is now up to 30% faster. This directly translates to
    encoding/decoding speed of variants (used extensively in the D-Bus/gvariant world). This is the
    path that saw the least optimization in 5.0.0.
  • We'll now be able to remove nom and minimal-lexical deps (recently introduced in 5.0.0).
    Apparently winnow was already our indirect dependency so no new deps needed.
• ➕ Add a direct dep on winnow.
• ➖ Drop now unneeded nom dependency.
