Build Vosk-API for FreeBSD 12.3 (and possibly later too).

Please review this script before executing. A number of packages

will be installed, and some soft links made in /bin and /usr/local/{bin,lib}.

Expect 20-120 minutes to build everything. Sudo is required for installing
10+
packages and making soft links.
