hermes@0.6.0 broke jsvu

[Mathias Bynens]

Looks like the Hermes team changed something about the way they publish new releases, causing jsvu to break:

$ jsvu hermes@0.6.0

Previous versions of hermes had hermes-repl for the REPL and hermes for the compiler. (facebook/hermes#17 (comment))

Starting with v0.6.0, it looks like the REPL is now called hermes, and the compiler is now hermesc.
