Null pointer when fetching an empty BLOB

[brunokoga]

According to the SQLite Documentation:

The return value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer

But this is the way SQLite.swift handles BLOB (on struct Cursor in Statements.swift):

  public subscript(idx: Int) -> Blob {
        if let pointer = sqlite3_column_blob(handle, Int32(idx)) {
            let length = Int(sqlite3_column_bytes(handle, Int32(idx)))
            return Blob(bytes: pointer, length: length)
        } else {
            fatalError("sqlite3_column_blob returned NULL")
        }
    }

Shouldn't the else return an empty BLOB (Blob(bytes: [])) in this case?

Good catch, just pushed a fix for this.
