Support for chunked upload

[maaaaz]

Hello @Densaugeo,

Your useful program does not currently support chunked upload.

In some cases, such as for instance uploading to a web server exposed by Cloudflare Tunnel, there is a strong limitation of the size of a file uploaded in a request. Without chunk upload, the limit is triggered.

Could you consider adding a chunked upload option in uploadserver ?

Cheers!

I haven't used Cloudflare much. What sort of restriction does it put on upload size?

I'm a little hesitant to add complexity, but I'd be open to it if a simple enough implementation can be found.

Something like 100 MB max per "file", "file" being a non-chunked upload.

I'd be open to it if a simple enough implementation can be found.

Could work if handling for partial failures and failures on later chunks can be squeezed in. Ideally I'd like the client to stay under one page of code - this project is intended to be dead simple and have few edge cases.

I'll leave this here in case I (or someone else) finds time.
