Support for Phi-2

[nndnnv]

Tried running phi-2 model, got this error:
error loading model: unknown model architecture: 'phi2'

llama.cpp already added support for Phi-2 model, so I guess a new LLamaSharp version (with updated llama.cpp binary) should add support as well, correct?

ggml-org/llama.cpp#4490

Yep we'll need to update the binaries to get support for Phi2. Latest update was last week (#361) (not yet released). So we'll probably pickup Phi2 support in another month or so at the next update.

Should be resolved in #479

0.10.0 just released, which includes Phi2 support.
