Chunked Uploads | Fix Upload Authentication

What does this MR do and why?

• Use Crafty's JWT authentication method for file uploads

• Splice files on the frontend to accept chunked uploads as well as bulk uploads

• Provide feedback on all upload pages

• Consolidate and improve speed on uploads.

• Resolves #263 (closed)

• Resolves #314 (closed)

• Resolves #353 (closed)

• Resolves #352 (closed)

• Eliminates the need for #179 (closed)

This has been tested through Cloudflare and works. There appears to be some sort of rate limit that will pause the requests for 10-20 seconds every x chunks, but the upload finishes successfully. They may just take longer through CF because of this apparent rate limit.
