Adds an internal type for opportunistic heap offload which uses `Box` when the `alloc` feature is available and falls back to stack allocation when it is not. So far it's only used for the `z` component of `Signature` but is useful elsewhere, e.g. for `VerifyingKey`. It's so generally useful it should probably get extracted somewhere, to `module-lattice` at the very least, but this is enough to get started.
RustCrypto: Signatures 
Support for digital signatures, which provide authentication of data using public-key cryptography.
All algorithms reside in the separate crates and implemented using traits from
the signature crate.
Crates are designed so they do not require the standard library (i.e. no_std)
and can be easily used for bare-metal or lightweight WebAssembly programming.
Crates
NOTE: for RSA signatures see https://github.com/RustCrypto/RSA
Usage
Crates functionality is expressed in terms of traits defined in the signature
crate.
License
All crates licensed under either of
