Tract

ONNX

* covered operators compatible with Operator Sets 9, 10, 11 (new) and 12 (new)

API Breaking

* Tensor::l1 method is gone

Windows

* Support for -gnu targets (non-mvsc).

Notable

* --cost now gives the number of parameters in the model
* SimpleState is clonable again (actually useful !)

* introduce `TypedModel::method.concretize_stream_dim`
* various pulsification bugfixes

* fix Reshape with TDim

Still no shortage of version numbers...

API Breakage

* NormalizedModel (and friends) are gone. They were only useful as a pre-pulse transformation pre-requisite that the current TypedModel (& co) meets.
* TypedModel::into_optimized() is gone. InferenceModel::into_optimized() stays as an end-to-end shortcut for simple cases. It does .into_typed()?.declutter()?.optimize()).
* TypedModel::codegen() is now ::optimize()

I wish I had seen these issues yesterday. Anyway, version numbers are cheap.

* Bumping minimum rust to 1.41

* CLI refactoring (hopefully stabilizing a bit?)
* `profile --bench` is now bench
* profile is now `dump --profile`
* cost is now `dump --cost`
* profiling is now done during a full net instead of per op
* new "compact" graph dumper, profile visual hints
* `dump --cost --profile --json` output profiling and cost information
* show logical names for ops instead of the Op struct names (not 100% sure it's right)
* criterion integration
* WASM support for tract-onnx and tract-tensorflow targets (CI)
* Convenience methods added to Models to allow model building in fluent style, up to Plan instantiation (SimplePlan now nicknamed RunnableModel). Non breaking.
* Support for ONNX bidi LSTM (CI), GRU and RNN (untested, consider alpha)
* Fixes around nets with a non trivial batch size (axis simplification code, matmul op fusion)
