Bump syn from 1.0.51 to 1.0.62 in /oak_loader

[dependabot]

Bumps syn from 1.0.51 to 1.0.62.

Release notes

Sourced from syn's releases.

1.0.62

• Republish to work around docs.rs bug rust-lang/docs.rs#1300

1.0.61

• Improve assertion failures on invalid use of Punctuated API (#970, thanks @​osa1)
• Add Lifetime::span and Lifetime::set_span accessors (#971)

1.0.60

• Provide an idiom for testing exhaustiveness of pattern matches on Expr, Type, Pat, Item, ForeignItem, TraitItem, and ImplItem (#694)

  match expr {
      Expr::Array(e) => {...}
      Expr::Assign(e) => {...}
      ...
      Expr::Yield(e) => {...}
  #[cfg(test)]
  Expr::__TestExhaustive(_) => unimplemented!(),
  #[cfg(not(test))]
  _ => { /* some sane fallback */ }
  
  }

  The above is the only supported idiom for exhaustive matching of those enum. Do not write anything differently as it is not supported.

  The conditional compilation on match-arms lets us fail your tests but not break your library when adding a variant. You will be notified by a test failure when a variant is added, so that you can add code to handle it, but your library will continue to compile and work for downstream users in the interim.

1.0.59

• Parse empty supertrait lists consistently with rustc (#952)
• Fix loss of span information on comma tokens inside of Type::Tuple during parse (#959)

1.0.58

• Allow literals to parse as a const generic path argument even without "full" feature enabled (#951)

  pub struct Struct {
      array: Array<10>,  // used to require `features = "full"`
  }

1.0.57

• Make Punctuated::new available as a const fn (#949)

1.0.56

• Add Error::into_compile_error

1.0.55

• Preserve None-delimited group around macro metavariable when parsing T<$ty> (#944, #945)

... (truncated)
