Release V0.7.0rc1: torch.compile, preserve axis identity, array api · arogozhnikov/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
