…d update documentation (#38)

* Improve ToString() performance by hinting JIT to not do bounds-checking later

* Update benchmark results in README.md with latest performance data. Add `AsByteSpan()` benchmark along with `ToByteArray()` benchmarks.

* Refine README: Add ULID vs UUIDv7 heading, badge for .NET AOT readiness, and lock-free synchronization details. Update PACKAGE.md as necessary.

….md`. (#35)

* Refactored ULID string formatting logic to remove redundant checks and improve overall performance. Added additional test for Unix timestamp and random input validation.

* Removed "readonly" marker from methods where it is not necessary.

* Updated README to clarify ULID advantages over GUIDs, highlight strict monotonicity, and address limitations in UUIDv7 implementations.

…ng()` (#29)

* Improved timestamp handling in `Ulid.New` implementation, and added test for timestamp and random validation. Rewrote ULID generation methods to use refs instead of Spans for performance.

* Refactor ULID parsing/encoding to use Unsafe.As/Add for direct memory access, improving performance and eliminating bounds checks.

* Updated benchmark results in README.

.NET 10 support (#23)

* Add .NET 10.0 support across projects, actions, and documentation; minor adjustments in README and validations.

* Enable manual workflow dispatch in build-and-test GitHub Action.

* Update README and dependencies for latest benchmarks

…andom` performance, and replaced `lock` with spinlock. (#18)

* Enhanced performance via `[MethodImpl(MethodImplOptions.AggressiveOptimization)]` for .NET Core 3.0+ methods.

* Replaced `lock` with lightweight spinlock for improved performance in `Ulid.New`.

* Refactored `FillTime` for simplicity and performance. Improved `FillRandom` performance by comparing timestamps as `ulong` values instead of as sequences of bytes. Updated benchmark results in README.

…ness (#17)

Introduces significant enhancements to the ULID generation mechanism, providing greater flexibility, modularity, and addressing potential predictability concerns in monotonic ULID sequences.

Features:
* Configuration Object for ULID Generation (`GenerationOptions`)
* Modularized Random Number Provider Implementations
* Implemented Random-Sized Incrementing for Monotonic ULID Generation

Deprecates:
* `public static bool Ulid.DefaultIsMonotonic { get; set; }`
* All public static `Ulid.New(..., bool? isMonotonic)` overloads.

Make Ulid AoT compatible (#12)

Mark Ulid library as AoT compatible.
Add AoT Console application to use Ulid in various ways to test AoT compatibility.
Added GitHub Action workflow to run the AoT Console application.
