Implemented NodeJS chunk upload

[Meldiron]

🚧 BREAKING CHANGE 🚧

This PR will require new usage.

Before:

storage.createFile( fs.createReadStream("file.png"); )

After:

storage.createFile( "file.png" )

This is required, because we need to create multiple read streams with different start&end pointers in case of chunk upload (over 5MB)

🚧 END BREAKING CHANGE

Snippet:

const sdk = require("meldicektesticek");

const client = new sdk.Client();
let storage = new sdk.Storage(client);

client
 .setEndpoint("http://localhost/v1")
 .setProject("dev")
 .setKey(
  "1174819a7d8c52d16d1eabe45773f5e16b05d7536e8b015b806a9c61e9673eefcb34006be50a8dd70aa96fc73ac1f5f99c7959cd7ccbc1a15aba64f33db7b38db2d914fb84c39a5d3316b8b941ed57d337346e07f0f82c2e0b68270a89bd9e2bbdd18527fce09441ddda283908252959dd5e70bd5185a1646bbce4b3b5274b53"
 );

let promise = storage.createFile(
 "vsetko",
 "unique()",
 __dirname + "/file.mp4",
 undefined,
 undefined,
 (data) => {
  console.log("D", data);
 }
);

promise.then(
 function (response) {
  console.log(response);
 },
 function (error) {
  console.log(error);
 }
);
