The rand crate generates cryptographically secure random numbers. As a result, it is slower, slower to build, and has a larger dependency tree. To my understanding of the Trace Context spec (https://www.w3.org/TR/trace-context/#privacy-of-traceparent-field), cryptographic security is not necessary for this field. This library can replace rand with a simpler crate, like fastrand: https://crates.io/crates/fastrand
