minarrow-pyo3 0.3.0

Changed

• Bumped minarrow dependency from 0.10.1 to 0.11.0.

Removed

• Unused nightly feature gates (allocator_api, slice_ptr_get,
  portable_simd) from the crate root. The underlying allocator-aware types
  are re-exported from minarrow, so the gates are not required at this
  crate's call sites.
