Document max length restrictions

Any idea on the maximum payload size?

I can successfully download a qr code with a URL that has 138 bytes (7-bit US-ASCII characters)this requires a json wrapper payload of 143-146 bytes.

I tried to adapt the 2nd example in https://github.com/Epicpkmn11/dsidl/wiki/Scripting with a destination filename but failed to read the QR code when the URL is 138 bytes. EDIT this is with https://github.com/Epicpkmn11/dsidl/releases/tag/v0.1.1

I think this means a limit of ~150 bytes. Thoughts?

Be great to get this documented.

Thanks @Epicpkmn11 for making this tool, works great! Not figured out how to get this to work with WEP (I have an idea to setup a temp/sandboxed router solely for DS gaming) but seems to work with WPA2 fine for me so far :-)
