Cannot build cargo-outdated with latest nightly rust release

[mikemadden42]

I cannot build cargo-outdated with latest nightly rust release. It looks like the stdsimd feature is missing.

$ lsb_release -sir
Ubuntu
22.04

$ arch
x86_64

$ cat rust-toolchain.toml
[toolchain]
channel = "nightly"
profile = "default"
components = ["rust-src", "rustfmt", "clippy", "rust-analyzer"]

Running cargo update fixed the build issue for me.

I suspect the outdated ahash crate is the root of the issue.
