Issue Description

Files larger than 512MB are not able to be uploaded to Parse Server as Parse.Files.

The files are converted to stings, which is more than Node can handle.

Steps to reproduce

Upload a file bigger than 512MB.

Actual Outcome

Error: Cannot create a string longer than 0x1fffffe8 characters

This appears to come from this line:
https://github.com/parse-community/parse-server/blob/6.3.1/src/Routers/FilesRouter.js#L175

Expected Outcome

The Parse.File to be created.

Environment

Server

• Parse Server version: 6.3.1
• Operating system: Linux
• Local or remote host (AWS, Azure, Google Cloud, Heroku, Digital Ocean, etc): Aptible

Database

• System (MongoDB or Postgres): MongoDB
• Database version: 4.0
• Local or remote host (MongoDB Atlas, mLab, AWS, Azure, Google Cloud, etc): Aptible

Client

• SDK (iOS, Android, JavaScript, PHP, Unity, etc): Android
• SDK version: 4.2.0

Logs

Start in src/Routers/FilesRouter.js around line 175 and inspect the createHandler path that converts uploaded file data to a string. Reproduce the failure with a file larger than 512MB, then verify that a Parse.File can be created without triggering Node's string-length error.
