1.0.0

Changes since 0.4.1:

• The public API hasn't changed for a long time, so the main purpose of this release is to "officially" stabilize it as-is.
• Prebuilt binaries are now published for more platforms, particularly AArch64. Thanks to @ddelange for implementing this.
• blake3.pyi (static typing stubs) now uses collections.abc.Buffer for bytes-like arguments. This is more correct and more permissive, but it means that static typechecking requires Python 3.12+.
