Does not detect truncated GitHub API blobs

[denizdogan]

We encountered a bug where the library says "Internal Error: No components founds!" even though the file is valid. It works with a local file.

We figured out that the problem comes from some response size limit in GitHub. It would be nice if the library would detect truncated responses, and tell the user about it, as such:

query {
  repository(name: "...", owner: "...") {
    object(expression: "<ref>:<specPath>") {
      ... on Blob {
        isTruncated /* this one does it */
        text
      }
    }
  }
}

The output is then:

{
  "data": {
    "repository": {
      "object": {
        "isTruncated": true,

Thanks!
