Why does "func NewP256Signer()" returns an "ed25519Signer"?

[cedricvanrompay-datadog]

From https://github.com/theupdateframework/go-tuf/blob/0e889ad1c/pkg/keys/ed25519.go#L18:

func NewP256Signer() Signer {
	return &ed25519Signer{}
}

Is this on purpose? Someone calling NewP256Signer would probably expect to get a signer using ECDSA over P-256 curve, and not a signer using Ed25519.

This is fixed now.

You can generate an ecdsa key with keys.GenerateEcdsaKey()
