Use System.Text.Json to serialize and deserialize JSON text

[GerardSmit]

This pull request replaces Newtonsoft.Json with System.Text.Json.

Do not merge this pull request yet. I don't have an Imghoard environment setup to test the changes I made. If I have a Imghoard environment and tested the changed I made I'll remove the draft status.

Looking through this, what made you remove Miki.Net.Http & Miki.Utils.Imaging.Headers?

As the former was planning to be used for rate limiting the client, and the latter is used to validate the image based on the only 4 available types that can be uploaded to Imghoard.

Edit: ignore The question Miki.Utils.Headers, the curse of a post wake up review made me over look it in formatters.

Looking through this, what made you remove Miki.Net.Http

The fact that it currently has a performance issue that I couldn't fix because I don't have access to it.

Whenever you call GetStreamAsync (which I wanted to use for deserializing the JSON) it calls SendAsync, which does the following:

httpResponse.Body = await response.Content.ReadAsStringAsync();

In other words, it calls both ReadAsStringAsync and ReadStreamAsync, which is unnecessary.

the curse of a post wake up review made me over look it in formatters.

Happens to the best of us 😄.

Hey @GerardSmit is this still a WIP?

[GerardSmit]

It is. I'll revert System.Net to Miki.Net.Http when https://github.com/Mikibot/MikiStd/pull/3 is merged.
