- Modified `llama_sample_token_mirostat` and `llama_sample_token_mirostat_v2` to take `ref float` instead of as a `float*`. Less pointers is always good.
 - Modified `llama_sample_repetition_penalty` and `llama_sample_frequency_and_presence_penalties` to take pointers instead of arrays. This allows the use non non allocating types (e.g. Span) instead of arrays
 - Modified higher level API to accept `Memory<int>` instead of `int[]`, which can be used to reduce allocations at call sites

ReSharper code warnings cleanup

ModelsParams record class

Improved Cloning

- Used those methods to add a `Clone` method to SafeLLamaContextHandle
 - Simplified `LLamaContext` by using the new methods
 - Sealed `LLamaContext` and `LLamaEmbedder`

Embedder Test

OldVersion obsoletion notices

- Minor changes to cleanup some of the compiler warnings

Changed type conversion

Type conversion is now done in the property rather than the utils class and uses the System.Convert class to ensure consistency.

- Equality, hashing etc all implemented automatically
 - Default values are defined in just one place (the properties) instead of the constructor as well
 - Added test to ensure that serialization works properly

Minor Code Cleanup

- Deleted `NativeInfo` (internal class, not used anywhere)

Added native symbol for CFG

Re-renaming some arguments to allow for easy deserialization from appsettings.json.

Grammar basics

Stateless Executor Fix

- Passing encoding in the `IModelParams`, which reduces how often encoding needs to be passed around

- Removed some unnecessary `ToArray` calls
 - Initial pass on LLamaStatelessExecutor, the context overflow management is broken but I think I found where it's ported from

- Converted `SafeLLamaContextHandle` to take a `ReadOnlySpan` for Eval, narrower type better represents what's really needed

renamed some arguments in ModelParams constructor so that class can be serialized easily
