warning: extra_unused_type_parameters in generated code

[tiziano88]

Started getting this warning from clippy with Rust 1.69 nightly:

parameter goes unused in function definition
  --> oak_sev_guest/src/guest.rs:45:17
   |
45 | #[derive(Debug, AsBytes, FromBytes)]
   |                 ^^^^^^^
   |
   = help: consider removing the parameter
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#extra_unused_type_parameters
   = note: `#[warn(clippy::extra_unused_type_parameters)]` on by default
   = note: this warning originates in the derive macro `AsBytes` (in Nightly builds, run with -Z macro-backtrace for more info)

Never mind, looks like a duplicate of #154
