Make opam-file-format work with BuckleScript

[wokalski]

opam-file-format is a parser for opam files. If it is compilable by BuckleScript, we save a lot of time when implementing #81.

If we compile it with Bucklescript we can drop the OCaml dependency and publish a package containing the JS output.

#81 depends on this one.

I have started working on this feature.

This one was trivial. opam-file-format works with BuckleScript out of the box. There's some problem with Pervasives module.

1. in_channel is an argument to Lexing.from_channel
2. in the simplest scenario you use OcamlParser.main
3. it takes lexbuf as one of its args
4. BuckleScript doesn't implement open_in yet.

The parser itself works though so this is a good first step.

The source is here, although it's probably gonna live in the esy at the end of the day.

Actually it's not a problem because we can create a lexbuf with a string. Even if there's no way to read a file into a string in BuckleScript we can resort to bs.raw.
