[BUG] Can't connect to websocket, The server returned status code '200' when status code '101' was expected

[steampoweredtaco]

A recent TikTok changed broke websocket connections that do not include version_code=180800 in the query parameters for the websocket url. This is breaking everyone's C# clients.

The library seems like it might be reusing the headers that it also uses for the web client which breaks with version_code in it (that was another bug we fixed recently).

A gross hack that fixes this that I confirmed on my end:

diff --git a/TikTokLiveSharp/Client/TikTokBaseClient.cs b/TikTokLiveSharp/Client/TikTokBaseClient.cs

                 {

I'm sure there is a better way to fix the code, but I'll leave it to ya'll @frankvHoof93

A quick note, it looks like TT is updating their backend requirements quickly and now the version may need to be 270000 .

Another note, it appears that the required value depends on knowledge only know to eulerstream... so we probably should hold off on patching this until we know the full story/fix.
