Configurable size for file uploading

It would be nice to use env variable such as MAX_FILE_UPLOAD to configure maximum file size.

Additional information : File limit is hard-coded in frontend and backend https://github.com/jhaals/yopass/blob/b43905591976caee9cd101ab39b7c002e2a21291/cmd/yopass-server/main.go#L26 Memcached max limit is 1 Mo, Redis has a 512 Mo limit.

The limit is also in the crypto, async crypto simply cannot encrypt big messages/files. For that you need a hybrid approach.

Actually you can adjust the memcached limit like this:

memcached -I 10m  # Allow objects up to 10MB

If you change the maxSize constant and run the yopass server with a bigger max-length then uploading bigger files is possible.

I don't know the exact limit for the crypto stuff though.

But having a configurable maxSize for file sizes would be absolutely possible, because I tried it in this PR: https://github.com/jhaals/yopass/pull/1154

That needs a rework though with validating the size on the server and returning an error to the client. If you feel like doing that @okolya then please go ahead! :)

@okolya If you want something that works rn you can check out a similar project I made, can configure the size there. https://github.com/cupcakearmy/cryptgeon

@jhaals are there any plans to support larger file uploads in the near future?
