Bump serde_derive from 1.0.68 to 1.0.91

[dependabot-preview]

Bumps serde_derive from 1.0.68 to 1.0.91.

Release notes

Sourced from serde_derive's releases.

v1.0.91

• Support deserializing from MapAccessDeserializer into an enum (#1522)

v1.0.90

• Add an attribute #[serde(crate = "path::to::serde")] which replaces the use of extern crate serde in the generated code; this is intended for crates that invoke Serde derives from a macro and need to refer to serde through their own re-export rather than requiring callers to list Serde in Cargo.toml (#1499, thanks @​sgrif)

  #[derive(Deserialize)]
  #[serde(crate = "__tw::codegen::serde")]
  struct S { ... }

  // expands to:
  impl<'de> __tw::codegen::serde::Deserialize<'de> for S {
      ...
  }

v1.0.89

• Implement Serialize and Deserialize for core::cmp::Reverse<T> (#1486, thanks @​vorot93)
• Fix a Clippy lint triggered within generated code involving flatten + deny_unknown_fields (#1492, thanks @​thomaseizinger)

v1.0.88

• Support flatten and skip_serializing / skip_deserializing attributes on the same field

v1.0.87

• Fix inclusion of tag in struct containing flattened fields (#1468, thanks @​jwillbold)

v1.0.86

• Implement Serialize and Deserialize for core::ops::Bound<T> (#1466, thanks @​0nkery)

v1.0.85

• Accept #[serde(alias = "...")] attribute on fields and variants which allows the same field or variant to be deserialized from any of multiple different names in the input (#1458, thanks @​Lymia)

  #[derive(Deserialize)]
  struct S {
      #[serde(alias = "old_name")]
      new_name: String,  // will deserialize from either of "old_name" or "new_name"
  }

v1.0.84

• Update example code in documentation to 2018 edition

v1.0.83

• Support a rename_all specification that applies only to the Serialize impl or only to the Deserialize impl (#1447, thanks @​vincascm)

... (truncated)
