Upgrade to libssl3? - libssl.so.1.1: cannot open shared object file: No such file or directory

Ubuntu 22.04 and later have moved from libssl 1.1 to libssl3, so attempting to start tunnelto on these machines yields a "libssl.so.1.1: cannot open shared object file: No such file or directory" error.

Workaround: build from source with the Rust version.

I'm sure older versions of Linux (maybe mainline Debian? Probably centos?) are still on libcrypto or libssl1 and don't know if there's any backwards compatibility, but it seems worth reporting.
