0.4.1

[0.4.1] - 2026-03-25

Fixed

• Fixed a few quirks on 32-bit platforms, in particular B-tree size estimation.

• Fixed panic due to non-ZST being sorted by offset before a ZST in the same
  position.

Changed

• mem_size_flat/mem_size_rec attributes are now
  mem_size(flat)/mem_size(rec). Warning are emitted when using the old
  syntax.

Improved

• More precise collection size estimation depending on the platform.
