Implement Example Program Using Ed25519 Signature Verification

[anthonyliriano]

We need an example program that demonstrates how to use the Ed25519 signature verification to spend custodied funds. This example should serve as a reference for developers looking to integrate Ed25519 signature verification into their Solana Program, particularly in the context of managing and spending custodied funds.
