    Scala implementation of https://github.com/bitcoin/bitcoin/blob/master/src/pubkey.cpp#L16-L165

    Parses correctly as well as poorly encoded DER signatures.

    "Supported violations include negative integers, excessive padding, garbage at the end, and overly long length descriptors."

    The signatures must still follow the following general format:

    0x30 | total length | 0x02 | R length | [R] \ 0x02 | S length | [S]

    IMPORTANT: Do not use this without further validation when validating blocks because BIP 66 requires that new signatures are verified to be strict DER encodings.
