v0.19.1

This release includes one significant change to the installer's behavior: it now sets always-allow-substitutes = true by default in nix.conf. Beyond that, changes include some additional README documentation of CLI flags and environment variables, new testing suites for ARM64, and a standard round of Rust dependency updates.
