Use rustls instead of OpenSSL; release 0.2.1

[saramaebee]

Summary

The v0.2.0 release build failed on x86_64-unknown-linux-musl: reqwest's default native-tls feature pulls in openssl-sys, which can't link when cross-compiling to musl (no musl OpenSSL on the runner). The gnu/macOS builds passed because they have system OpenSSL.

Switch reqwest to rustls-tls with default-features = false (keeping json/gzip/brotli/deflate/charset/http2). This removes openssl-sys from the tree entirely, so musl builds cleanly and no target depends on system OpenSSL anymore. Bumps version to 0.2.1.

Test plan

• cargo build and the full test suite (103 + integration tests) pass.
• openssl-sys gone from Cargo.lock; rustls present.
• musl cross-compile proof comes from the v0.2.1 release run after tagging.

After merge

Tag v0.2.1 on main to trigger the release (the v0.2.0 tag's build failed, so nothing was published under 0.2.0).

Walkthrough

This PR updates the Cargo.toml configuration for the fossapi crate. The package version is bumped from 0.2.0 to 0.2.1. The reqwest HTTP client dependency is reconfigured to disable default features and explicitly enable rustls-tls alongside json, gzip, brotli, deflate, and http2 features. This configuration change allows the crate to use Rust-native TLS instead of the default OpenSSL for cross-platform compatibility.
