A splitted signature is a binary representation of a signature with a fixed 64 bytes suffix and a possible prefix.
split_signature s splits the signature s into {prefix; suffix} where suffix is the fixed 64 bytes suffix of s and prefix are the remaining preceding bytes if any.
of_splitted s reconstructs a signature from a splitted one, if possible.

module Of_V0 : sig ... endThis module provides conversion functions for values (of keys and signatures) of the module Signature_V0. Note that these functions are total because Signature_v1 supports more signature kinds than Signature_v0.
