Feature/CPU init

[ivarflakstad]

Initial steps adding CPU implementation for ratchet.

todo:

• [x] Simple POC
• [x] Figure out a decent pattern that allows us to support all dtypes

Ops implemented in this first PR:

• Binary
• Cast
• Unary
• Select

Currently we are using Tensor::to_vec<T> to access the data in the cpu buffer. At some point we should look into "peeking" into the storage as a slice instead. Probably at the same time as introducing vectorized operations and wasm.
