What is the new behavior?

Functionality to handle GZip compress/decompress. Placed it in the encode/decode (couldn't find a better place?). Functionality is very similar to HTML encoder/decoder (buttons/fields) but instead does standard .NET GZip

Other information

It is using the "CanBeTreatedByTool" to check if clipboard data trimmedData.StartsWith("H4sI");
Sorry to say I was unable to get the icon functional. Not very good at svg 😞 Maybe someone could help out ?

I have seen that you add the localization file for English only. 
Please add the file for the other languages too

Just copy en-US file --> all folders or should I actually google translate all langs ?

Just empty files or should I actually google translate all langs ?

Just copy the English file in the other language, this way the user who want to update the localization can update the file directly

I was working on this same feature yesterday/today in my free time, and created issue #217 and PR #218 for my changes before seeing this PR. I have mentioned the issue above. Not sure what will happen now... but will leave my changes open as I went about adding it as an option to the existing Base64 tool as they are closely linked in this scenario.

@jedjohan regarding getting the icon glyph to work, I had the same exact issue! I installed the included FluentSystemIcons-Regular.ttf font and used an app (Character Map UWP) to browse through the symbols for the right icon :)

@AHollowedHunter ahh, that must mean its a really good tool to have, 2 gzip PRs in the same day 😄 I don't really care where it ends up (even though I don't really agree that base64 is linked to gzip compression). Guess its a good thing to try to reduce the number of separate tools in a UX sense ? Thanks for the icon tip ! Don't know if I should spend time on it though, depending on which PR that will get merged.

Hello,
Thank you for your contribution! Overall, it looks good to me. Just a few comments here and there. :-)
I will let @btiteux give the final approval and merge.

Looking forward to get this tool :D As you said, 2 PR for the same thing the same day means something.

As @btiteux mentioned in the other PR, we will keep this one because we see an advantage at having this feature as a separated tool from Base64 Encoder/Decoder => we can, in the futrue, extend it to compress/decompress some gzip files.
