v0.14.0

Summary

This release marks the debut of our CubeCL integration, which brings cross-platform GPU programming capabilities directly to Rust.
With CubeCL now supporting both CUDA and WebGPU, Burn benefits from a new CUDA backend that can be enabled using the cuda-jit feature.
Please note that this backend is still considered experimental, and some operations, particularly those related to vision, may experience issues.

Additionally, this release features significant enhancements to ONNX support, including bug fixes, new operators, and improvements in code generation.

As always, it also includes numerous bug fixes, performance enhancements, new tensor operations, and improved documentation.

Burn 0.14.0 introduces a new tensor data format that significantly enhances serialization and deserialization speeds and introduces Quantization, a new Beta feature included in this release. The format is not compatible with previous versions of Burn, but you can migrate your previously saved records using this guide.
