refactor: replace FastNoise implementation with fastnoise-lite

[juyonLee00]

What

Replaces the legacy FastNoise implementation in bracket-noise with a compatibility wrapper backed by fastnoise-lite.

Why

The existing fastnoise.rs file was maintained directly by implementing custom noise algorithms.
This change reduces maintenance costs by delegating consistent noise generation to fastnoise-lite. Additionally, the existing wrapper API is retained.

Some existing variations are mapped to similar variations available in fastnoise-lite.

• Simplex / SimplexFractal -> OpenSimplex2
• Cubic / CubicFractal -> ValueCubic
• RigidMulti -> Ridged
• Billow -> PingPong
• Natural cellular distance -> Hybrid

Some existing settings are retained for API compatibility even if fastnoise-lite does not provide a direct equivalent.

• Interp is stored but not forwarded to fastnoise-lite.
• cellular distance indices are stored but not forwarded to fastnoise-lite.
• the public seed API remains u64, while fastnoise-lite uses i32, so very large seed values may be truncated.

WhiteNoise remains implemented locally because fastnoise-lite does not expose a direct WhiteNoise noise type.

The base frequency remains at 0.0 to maintain the previous bracket-noise initialization behavior.

Adds fastnoise-lite as a new dependency for bracket-noise.

closes #22

bracket-noise/Cargo.toml (1)

19-19: Fix verification: fastnoise-lite = "1.1" needs crates.io version/API confirmation; security advisories check returned none.

• Security advisories: GitHub GraphQL query for fastnoise-lite returned no securityVulnerabilities entries.
• Crates.io versions: the crates.io API fetch/parsing failed (jq: Cannot iterate over null), so the existence of fastnoise-lite 1.1.0 and the presence of newer versions (beyond ^1.1 allowing <2.0.0) can’t be concluded from the current results.
• The review request should be re-run with a working crates.io API parse (or a fallback endpoint) to list available versions and confirm 1.1.0 exists.

Poem

A rabbit hops through the crate today,
Discovering fastnoise-lite came to play,
No need to build what others have done,
One line of deps, and noise-building's fun! 🐰✨
