Fix missing library name prefix for cuda

Checkout specific ref for llamacpp when building native libs

Use llama instead of libllama in `[DllImport]`

This results in windows users not needing to rename the DLL. This allows native llama builds to be dropped in, even on windows.

I also took the time to update the documentation, removing references to renaming the files, since the names now match.

Fixes #463

LLamaBatch Grow n_seq_max automatically

- Growing more than double, if necessary

- Added `logits_i` argument to `Context.ApplyPenalty`
 - Added a new exception type for `llama_decode` return code

Improved the BatchedDecoding demo

- using less `NativeHandle`
 - Using `StreamingTokenDecoder` instead of obsolete detokenize method

LLamaBatch Automatically Grow Capacity

- Added a `DecodeAsync` overload which runs the work in a task
 - Replaced some `NativeHandle` usage in `BatchedDecoding` with higher level equivalents.
 - Made the `LLamaBatch` grow when token capacity is exceeded, removing the need to manage token capacity externally.

Managed `LLamaBatch`

Added a check for EOS token in LLamaStatelessExecutor

Tokenizer Fixes For Issue 430

- Properly displaying `LLamaToken`
 - Removed all tokenisation code in `SafeLLamaContextHandle` - just pass it all through to the `SafeLlamaModelHandle`
 - Improved `SafeLlamaModelHandle` tokenisation:
   - Renting an array, for one less allocation
   - Not using `&tokens[0]` to take a pointer to an array, this is redundant and doesn't work on empty arrays
