Adapt JS bindings for WASM module to pass files as byte array from browser extension

@jerinphilip There is another issue in this repo #59 that you created and sounds similar to me. I am closing that one.

So what i'm thinking is having something like

class marian_model {
   explicit marian_model(const void * model_bytes, const size_t model_bytes_size, const void * shortlist, const size_t shortlist_size,  const void * vocab, const size_t vocab size) {
                 validate_model_integrity();
                 validate_vocab_integrity();
                 validate_shortlist_integrity();
                 }
    marian_model() = delete;
};

Maybe include the config to it as well, and do a sanity-check that all the files are correct. Or use checksums for validation..

I think you meant const void *

• Write bindings for AlignedMemory class
• Adapt bindings of TranslationModel class to use AlignedMemory for passing model and shortlist bytes
• Modify wasm test page to:
  • Load both model and shortlist file from local machine (instead of emscripten’s emulated file system)
  • Read these files into buffer and populate AlignedMemory instances with them
  • Provide these AlignedMemory instances while constructing TranslationModel object
  • Change config string appropriately (remove model and shortlist entry from it)
• Test whether both model and shortlist files are successfully being passed as bytes from wasm test page
• Test from wasm test page whether it performs inference
  • Test for at least 1 direction (e.g. ES->EN)

• Perform all tasks for passing vocabulary files as bytes as well
