AWS Nitro Enclaves in Deno/Rust

Near-zero dependency example of how to use AWS Nitro enclaves from Deno. Can serve as a code sample or a blueprint to understand the whole process, because I found the AWS documentation and process quite unclear and over-engineered. Parts of the code (the code to access the Nitro Secure Module and the HTTP Proxy that connects on a VSOCK) are written in Rust and accessed in Deno through FFI.
