Raku binding to optimized C library for ECDSA

Raku binding to optimized C library for ECDSA signatures and secret/public key operations on curve secp256k1.

Synopsys

my $data = {
    key => '6fcc37ea5e9e09fec6c83e5fbd7a745e3eee81d16ebd861c9e66f55518c19798',
    msg => '1c8aff950685c2ed4bc3174f3472287b56d9517b9c948127319a09a7a36deac8'
};

my $secp256k1 = Bitcoin::Core::Secp256k1.new;
my $signature = $secp256k1.ecdsa_sign(:privkey($data<key>), :msg($data<msg>));

$signature.gist.say;

Further work

For now Bitcoin::Core::Secp256k1 module does not cover full secp256k1 API in C, so I'm working on this and will deliver complete binding ASAP.
