CLI resolver has no documentation

[alerque]

As I posted on discourse I'm looking for a basic CLI to query a message from *.ftl files. I finally figured out how to at least compile the parser and resolver binaries. The former was somewhat self-explanitory as it responded to a --help flag, and seems to do what it says on the tin. Pass it a single argument of at FTL file name and get an parsed AST representation back on STDOUT. Okay, but what do I do with resolver? It doesn't show any help messages, clearly is waiting for something on STDIN, but crashes no matter what I pass it.

• [ ] The link in the Readme should be fixed as it currently links to something on crates.io that doesn't exist.
• [ ] A help message of some kind should be added that explains the usage, what input it expects and what output can be achieved.
• [ ] CLI tool usage should be mentioned somewhere, maybe in the main rust docs? I don't know where actually, but I don't see it anywhere the project is talked about.

yeah, the cli tooling is in a very 0.0.1 stage :) I just didn't have time to put work into it yet.
