Einops

Major changes:

- `torch.compile` just works, registration of operations happens automatically
- JAX's distributed arrays can use ellipses, and in general ellipsis processing now preserves axis identity. This involved changing internal gears of einops.
- Array API: `einops` operations can be used with any framework that follows the standard (see `einops.array_api`)
- Python 3.7 is dead. Good bye, you were great at the time
- Gluon is dropped as previously announced
- reduce/repeat/rearrange all accept lists now

pre-release is published to allow public testing of new caching logic (pattern analysis is now dependent on input dimensionality to preserve axis identity).

- einops layers perfectly interplay with torch.compile
- einops operations needs registration: run `einops._torch_specific.allow_ops_in_compiled_graph()` before `torch.compile`
- paddle is now supported (thanks to zhouwei25)
- as previously announced, support of mxnet is dropped

Announcement

Sunsetting experimental mxnet support: no demand and package is outdated, with numerous deprecations and poor support of corner cases. 0.6.0 will be the last release with mxnet backend.
