The most recent commit push fixes two problems:
* we would leak `Py_buffer` objects when importing a `nb_buffer_info`, because we didn't ever call `PyBuffer_Release`.
* there was a use-after-move in `nb_buffer_info` when exporting a buffer because the shape and strides pointed to the contents of a `SmallVector` which was then moved.
