We should be doing what tcllib does in these cases. librivetparser includes a
C implementation for parsing Rivet documents, but we have a Tcl version in a
package that can be loaded in case the compiled version is unavailable. They
should be the same command name.
Tcllib does this everywhere. If we can compile one, we will. If we can't, we
fall back to a slower, Tcl-only implementation of the same command.
