Create a tsickle-cli that depends on tsickle

[evmar]

Tsickle does the annotation magic. But to use it you wanna run Closure in a complicated way, so in principle we should depend on google-closure-compiler. But that brings in a million other dependencies that are all unrelated to annotation.

The solution: make a tsickle-cli package that manages running things. Users like Google-internal tsc_wrapped and Angular's builder will likely not need tsickle-cli.

we do now depend on google-closure-compiler so I think this is obsolete?

[evmar]

The idea in this bug was that tsickle itself shouldn't depend on google-closure-compiler (since you don't need it if you're just using tsickle to transpile), but rather there should be a tsickle-cli package that uses both tsickle and the compiler.

It seems like @jjudd fixed this in #153.
