* Updated binaries to llama.cpp `3ab8b3a92ede46df88bc5a2dfca3777de4a2b2b6` (build run: https://github.com/SciSharp/LLamaSharp/actions/runs/8118890586)

* Added abort callback

* Added properties to get/set thread count on `LLamaContext`

* Fixed LLamaLogLevel numbering

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
