Orion version: 0.2.5

Current behavior: not compiled

Expected behavior: compiled

Steps to reproduce:

git clone git@github.com:gizatechxyz/orion.git
cd orion
scarb cairo-test -f multiple_linear_regression_test

The generic type T in the code below occurs the compile error

	impl TensorSerde<T, impl TSerde: Serde<T>, impl TDrop: Drop<T>> of Serde<Tensor<T>> {
	fn serialize(self: @Tensor<T>, ref output: Array<felt252>) {
	self.shape.serialize(ref output);
	self.data.serialize(ref output);

	let shape: Span<usize> = Serde::<Span<usize>>::deserialize(ref serialized)?;
	let data: Span<T> = Serde::<Span<T>>::deserialize(ref serialized)?;

Hello !
That's because Orion supports scarb 2.6.4, not 2.7.0.

We're working on a complete redesign of Orion, which will be much more efficient with a different approach instead of using ONNX. You can find this in the cleaning branch. But please have in mind that it's not ready yet, and there's still work to be done. I think I'll be releasing the new version in the next couple of weeks.

I see that you're preparing a benchmark @c0np4nn4, happy to discuss further if you need to know more :)

This doesn't seem too complex as well. Recently just learned Rust and Cairo and would love to take up this issue
