`cargo install mdbook-epub` is broken

[nnethercote]

When I run cargo install mdbook-epub I get this compile error:

   Compiling mdbook-epub v0.4.31
error[E0277]: `?` couldn't convert the error to `Error`
  --> /Users/njn/.cargo/registry/src/index.crates.io-6f17d22bba15001f/mdbook-epub-0.4.31/src/config.rs:34:63

   |                                                               ^ the trait `From<toml::de::Error>` is not implemented for `Error`
   |
   = note: the question mark operation (`?`) implicitly performs a conversion on the error value using the `From` trait
   = help: the following other types implement trait `From<T>`:
             <Error as From<SemVerError>>
             <Error as From<ReqParseError>>
             <Error as From<Box<ureq::Error>>>
             <Error as From<epub_builder::Error>>
             <Error as From<mdbook::errors::Error>>
             <Error as From<ureq::Error>>
             <Error as From<RenderError>>
             <Error as From<toml::de::Error>>
             <Error as From<std::io::Error>>
   = note: required for `Result<config::Config, Error>` to implement `FromResidual<Result<Infallible, toml::de::Error>>`

I see this with rust 1.71 and nightly 1.73.

This caused CI breakage for me here: https://github.com/nnethercote/perf-book/actions/runs/5572424446/jobs/10178452751. I will have to disable the epub build for the Rust perf-book because of this :(

Thank you for reporting. I will handle that and release new version.

@nnethercote Tested latest 0.4.32 version it was installed without errors on my linux.

Thanks! I was able to re-enable ePub for the Rust perf-book.
