Maximize URL length for sharing workflows

[fsteeg]

• Use max settings that work with Firefox, Chrome, and our backend server
• Look into possible string compression algorithms to use on the query params

The current status of this issue (on branch 80-maximizeUrlLength):
I found out that there is a problem opening the share link of this example. When the query params contains a url the url is not properly query encoded. This seems to be a problem of the used library lambdaisland.uri. BUT I testet a much shorter example with an url and although the url was not properly encoded, the share link can be openend (I tested with the workflow link). So I don't know what's the problem with the given example.
I didn't really start with the second part of the issue but here is what I planned to do:
I didn't found a library which works for clojure and clojurescript, so I decided to use Java classes (Deflater and Inflater) and a Javascript lib (not determined which but there are some) to use the zlib algorithm.
Problems I see:

1. after encoding the string there is a byte array, how to convert the byte array in a string again to use it for the url
2. like most compression algorithms there is real compression when the input is large enough. Should only be compressed when the input is large enough and how to mark that?

I hope this information helps to finish what I couldn't finish.

The current state looks good and seems to work well with larger examples, see the (work in progress) workshop examples deployed at https://test.metafacture.org/playground/ (Load Examples -> workshop).

Using string compression was just an additional idea, I suggest we skip that for now. Regarding the issues with longer links and URLs, I think we should look into that when it comes up in a concrete use case.

For now, this is a big step forward to creating useful examples for the workshop and beyond, so I think we should merge and deploy that state to production. Assigning @TobiasNx for functional review.

The examples look good. It seems that the changes helped with longer URLs/examples.
I agree with your suggestion to put further changes for longer exapmles/urls on hold for now.

Merged 80-maximizeUrlLength with fafc143.

Deployed to https://metafacture.org/playground, closing.
