⚠️ hugr breaking changes

--- failure inherent_method_const_removed: pub method is no longer const ---

Description:
A publicly-visible method or associated fn is no longer `const` and can no longer be used in a `const` context.
        ref: https://doc.rust-lang.org/reference/const_eval.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.31.0/src/lints/inherent_method_const_removed.ron

Failed in:
  ConstF64::new in /tmp/.tmpwo5blB/hugr/hugr/src/std_extensions/arithmetic/float_types.rs:43

--- failure struct_missing: pub struct removed or renamed ---

Description:
A publicly-visible struct cannot be imported by its prior path. A `pub use` may have been removed, or the struct itself may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.31.0/src/lints/struct_missing.ron

Failed in:
  struct hugr::ops::constant::ExtensionValue, previously in file /tmp/.tmpq1W6bC/hugr/src/ops/constant.rs:184
