Add Preset Arena results

[phiharri]

First pass at including presets from oobabooga's preset arena experiment (https://github.com/oobabooga/oobabooga.github.io/blob/main/arena/results.md)

sampler_order adjusted to put repetition_penalty at the front to better match the default textgen-webui / llama.cpp ordering, hopefully!
