Remove transitive dependency on mio

[SandroHc]

Removes the transitive dependency on mio. This allows projects targeting wasm32-unknown-unknown to compile.

The mio dependency is being brought in via: cornucopia_async→tokio-postgres→tokio-postgres/runtime→tokio/net→mio. By disabling the default features of tokio-postgres, we disable its runtime feature.

axum's comment on mio:

mio, tokio's IO layer, does not support the wasm32-unknown-unknown target which is why this crate requires default-features = false for axum.

Reproduction Steps

1. Install the "wasm32-unknown-unknown" target
   rustup target add wasm32-unknown-unknown
2. Create a dummy WASM library
   cargo install cargo-generate && cargo generate --git https://github.com/rustwasm/wasm-pack-template
3. Add "tokio-postgres"
   cargo add tokio-postgres@0.7.11 --no-default-features --features js
4. Confirm that project builds
   cargo build --target wasm32-unknown-unknown
cargo tree --target wasm32-unknown-unknown --invert mio (no matches is what we want)
5. Add "cornucopia_async"
   cargo add cornucopia_async@0.6.0 --no-default-features
6. Project no longer builds
   cargo build --target wasm32-unknown-unknown
cargo tree --target wasm32-unknown-unknown --invert mio
