The equivalents of these types used to live in the `ecdsa` crate, but were removed in this PR: RustCrypto/signatures#96 The goal of that PR was to reverse the previous relationship where the `ecdsa` crate depended on the `k256`/`p256`/`p384` crates, and instead have the curve implementation crates consume the `ecdsa` crate as an (optional) dependency. It makes each curve implementation a one-stop-shop for everything related to that curve, while allowing the ECDSA crate to provide some common functionality like ASN.1 (de)serialization, in addition to allowing it to export "primitive" traits which can be used with the goal of a reusable high-level ECDSA implementation which is generic over elliptic curves. This commit ports over equivalent types that were removed in `RustCrypto/signatures#96`, but also incorporates these changes: RustCrypto/signatures#98 Where the `ecdsa` crate previously had `Asn1Signature` and `FixedSignature` types generic over a curve, the PR above refactored it to make the "fixed" form the preferred `Signature` type, and refactoring ASN.1 DER support into an `ecdsa::asn1::Document` type. The nice advantage of that approach is it means the curve implementations no longer need to worry about an `Asn1Signature` type and can focus on `ecdsa::Signature` as the type they need to support.
