use dicom-rs with wasm bindgen about dicom-rs

Thank you @Enet4

Yeah dropping the first 128 bytes did it

    let mut file = Cursor::new(&slice[128..]);

    let obj = from_reader(&mut file).unwrap();

    let patient_name = obj.element_by_name("PatientName").unwrap().to_str().unwrap();

    console::log_1(&patient_name.to_string().into());

Thank you for the example! from_reader does not expect a preamble, which is probably what made the operation fail. Can you try and skip the first 128 bytes before calling from_reader?

I agree that the ergonomics of this API can be improved here. At some point the options builder pattern might be more interesting here.

Closing, as the main concern appears to have been resolved, and the current behavior of the API is by design. Improvements to the API can be suggested in #43.
