Replace serdi with more fine-grained tools

Especially with the new functionality, the complexity of the command-line
interface alone was really becoming unmanageable.  The serdi implementation
also had the highest cyclomatic complexity of the entire codebase by a huge
margin.

So, take a page from the Unix philosophy and split serdi into several more
finely-honed tools that can be freely composed.  Though there is still
unfortunately quite a bit of option overlap between them due to the common
details of reading RDF, I think the resulting tools are a lot easier to
understand, both from a user and a developer perspective.
