0.6

This release marks the addition of the [SynSense Speck chip](https://www.synsense.ai/products/speck-2/) (via [ZMQ](https://zeromq.org/)) and the [EVT3 Metavision](https://docs.prophesee.ai/stable/data/encoding_formats/evt3.html) file format.
We also implemented a rudimentary event viewer, requiring SDL2 as dependency.

Additionally, we found and resolved a memory leak when streaming tensors to the GPU.

0.5.1

The most significant change in this release is the migration to the [DLPack](https://github.com/dmlc/dlpack) in-memory structure via [nanobind](https://github.com/wjakob/nanobind). Briefly speaking, this means cleaner integration with numpy and native integration with device tensors, via accelerators such as PyTorch or Jax. In practice, we can now remove heavy dependencies because we hand off event data solely based on their memory pointers, without requiring large library APIs.

This release took a while, but it's worth the effort, and there are many future enhancements in the works. For instance, support for Inivation and Prophesee cameras, support for additional file formats, and performance improvements. :rocket:

A *big* thank you to stevenabreu7 for helping with M1 support, cameron-git for efforts around documentation, API design, and reviews, and cantordust for participating in API design, reviews, and lively discussions about C++ shenaningans :heart:

0.4.0

This release contributes performance improvements for the GPU accelerated tensor code and robust continuous integration builds, so we can ensure that AEStream works correctly across multiple versions of OSs and Python

Specifically, we have
* Split CPU and GPU builds, which allows us to test them independently
* Migrated to scikit-build to support matrix builds in continuous integration
* Added the `aestream` binary on `pip install`, so users can avoid cmake'ing the project from source
* Performance improvements for assigning event-data to CUDA tensors
