Incorrect behavior when using `from_ec_der` with `rust-crypto` provider

[OmniacDev]

When using DecodingKey::from_ec_der with the rust-crypto provider, it internally parses using from_sec1_bytes, instead of from_public_key_der.

jsonwebtoken/src/crypto/rust_crypto/ecdsa.rs

Line 60 in 9934c7f

<$verifying_key>::from_sec1_bytes(decoding_key.as_bytes())

So this, which is expected to work, fails:

let key: p384::ecdsa::VerifyingKey = ...;
let decoding_key = DecodingKey::from_ec_der(key.to_public_key_der().unwrap().as_bytes());

But this succeeds:

let key: p384::ecdsa::VerifyingKey = ...;
let decoding_key = DecodingKey::from_ec_der(&key.to_sec1_bytes());
