The `lazy_static` package does not work well in `no-std`: it requires
`spin_no_std` feature, which also will propagate into `std` if enabled.
This is not what we want.
This PR removes public/private key hash-maps and replaces them with
simple static byte arrays.
`&T` versions of `AsRef/Deref/From` traits implementation were removed.
Little const helper for converting hex strings into array during compile
time was also added. (somewhat similar to _hex_literal_).
