⚠ BREAKING CHANGES

• Hugrs now define an entrypoint in addition to a module root.

• std.collections.array.get now also returns the passed array as an extra output.
• ArrayOpBuilder was moved from hugr_core::std_extensions::collections::array::op_builder to hugr_core::std_extensions::collections::array.
• Functions that manipulate runtime extension sets have been removed from the Rust and Python code. Extension set parameters were removed from operations.
• values field in Extension and ExtensionValue struct/class removed in rust and python. Use 0-input ops that return constant values.
