* Add support for loading Fortran contiguous tensors
This commit introduces the ability to handle Fortran contiguous tensors in the tensor loading process. Previously, the code only supported loading tensors that were contiguous in memory, failing with an error for non-contiguous tensors. With this update, tensors identified as Fortran contiguous (column-major order) are now correctly handled by reversing their dimensions after loading. This enhancement ensures broader compatibility with different tensor layouts, improving the robustness of tensor loading operations.
- Check if a tensor is Fortran contiguous using the `is_fortran_contiguous` flag.
- For Fortran contiguous tensors, reverse the dimensions after loading to correctly represent their layout in memory.
- Continue to bail out with an error for tensors that are neither C contiguous nor Fortran contiguous, maintaining the previous behavior for non-contiguous tensors without explicit support.
This change addresses the issue of loading Fortran contiguous tensors, which was previously unsupported, thereby extending the functionality of the tensor loading mechanism to accommodate a wider variety of tensor layouts.
* Add reshape step to handle fortran contiguous case
* Skip fortran contiguous fix if rank is < 2
* Fail on rank 0, 1 if contiguous
`candle-nn` already exposes a trait to define custom backends. However,
it's not possible to actually construct a `VarBuilder` with a custom
backend because the constructor is not exposed.
This change makes the constructor public and renames it from `new` to
`from_backend` to avoid that it is seen as the primary
constructor (which could be confusing to users).
* Supports more audio formats
* Simplify the handling of the different buffer types.
* Check the sample rate.

Update the source of the configuration_mixformer_sequential.py
It has been removed, therefore, it is still available in this -> d38e6f954ec29b96fe2cf033937dad64e279b5d9
* Metal quantized modifications proposal.
- Add a device param, wherever needed.
- Create new QMetal storage thing that implements QuantizedType.
- Update everywhere needed.
Fix Python.
Fixing examples.
Fix: fmt + clippy + stub.
Moving everything around.
Only missing the actual implems.
Fixing everything + adding dequantized kernels.
More work.
Fixing matmul.
Fmt + Clippy
Some clippy fixes.
Working state.
Q2K Metal -> Bugged (also present in GGML).
Q4K CPU -> Bugged (present previously, new test catch it).
Q5K CPU -> Bugged (present previously).
Q8_1 Both -> Never really implemented it seems
Q8K metal -> Never implemented in metal
Fixing Q2K bug (present in ggml).
* Cleanup.
