Names `to_k`, `to_q`, `to_v`, `to_out` cause issues

[JamesDeAntonis]

Hi Lucid,

Hope all is well. Is there any need to have the q, k, v, o be named to_k, to_q, to_v, to_out? This causes lots of incompatibility with huggingface, since they call them q, k, v, o. Any chance we could change this to the HF convention?

Thanks!
