Are you able to maintain this part of code if pycraft upgrades and changes related codes in the future?

The part of ClientSettingsPacket code is hard-coded, which is not good in my opinion. Things like client view distance or something will somehow affect the recording

Sadly I'm not sure, but I'll try, so maybe you'd better not to merge into master. I just hope this branch may help those who are using PCRC with authlib-injector.

Maybe it can be configured with conf.json? Currently I haven't seen any codes in PCRC to configure it, so I guess these parameters are set as default now. However I didn't find out which is the default value of view distance.

I'll try to make them editable as long as I have time.

Test is REQUIRED before merging!

I tried to do some easy things on reading conf.json, but do not have a chance to test it since our server is paused (due to Graduate Entrance Exam). And I also cannot decide which setting should be added into the conf.json.
