Crisp Status Local v1.2.1

• Move away from native-tls to rustls, which makes MUSL builds independent from the OpenSSL version installed on the host system (a MUSL binary is now much more portable; and as a side-effect of moving away from OpenSSL, the MUSL binary shrinks from approximately 3.6MB to 1.5MB).
• The binary shipped in the Docker image is now statically-linked, which helps shrink the compressed Docker image size down from approximately 40MB to 900KB.
