Nirtorch

This release adds name checking to the generated Python code to avoid clashes with keywords

A minor release to improve documentation and simplify default values in API

What's Changed
* Improved documentation and default dictionary mapping by Jegp in https://github.com/neuromorphs/NIRTorch/pull/31

This release migrates torch graph parsing and NIR interpreting to `torch.fx`. Specifically, we introduce new API functions `nir_to_torch` and `torch_to_nir` and deprecates the old `load` and `extract_nir_graph` functions.

The main advantages of torch.fx is
1. Simplicity, since their API is close to a raw graph (which aligns well with NIR) and
2. Tracing that is purely symbolic so we can avoid passing mock data into the parsing functions.
3. Additionally, this lets us leverage pattern matching and similar abstract graph operations in the future.

* Ports the graph tracing to torch.fx by Jegp in https://github.com/neuromorphs/NIRTorch/pull/28
* Updated README and version numbering by Jegp in https://github.com/neuromorphs/NIRTorch/pull/29
