⚠ flickzeug breaking changes

--- failure constructible_struct_adds_field: externally-constructible struct adds field ---

Description:
A pub struct constructible with a struct literal has a new pub field. Existing struct literals must be updated to include the new field.
        ref: https://doc.rust-lang.org/reference/expressions/struct-expr.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/constructible_struct_adds_field.ron

Failed in:
  field FuzzyConfig.similarity_threshold in /tmp/.tmpytJT3B/flickzeug/src/apply.rs:166

--- failure enum_changed_kind: pub enum changed kind ---

Description:
A public enum has been replaced by a different kind of item at the same path, which breaks code that relied on the enum's variants and representation.

       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/enum_changed_kind.ron

Failed in:
  enum flickzeug::ParsePatchError became struct in /tmp/.tmpytJT3B/flickzeug/src/patch/parse.rs:45

--- failure enum_variant_added: enum variant added on exhaustive enum ---

Description:
A publicly-visible enum without #[non_exhaustive] has a new variant.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#enum-variant-new
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/enum_variant_added.ron
