No config files loaded, not just global config

[Philipp5796]

Describe the bug
With the bugfix for #190, no config files are loaded, not just the global. This way, it is no longer possible to use custom yt-dl parameter.

To Reproduce
Steps to reproduce the behavior:

1. Place a yt-dlp.conf file next to the exe in the directory
2. Download using the GUI

Expected behavior
Add a checkbox to the settings, so the user can enable and disable to load configs.
For new users, the default should be to disable configs
OR
Check if a yt-dlp.conf file is present in the application folder, next to yt-dlp.exe
if not found: use --ignore-config to disable global configs
if found: load this config file with --config-location, as written in #190

It should also pay attention to its own youtube-dl.conf file

the processing of further global configs can be prevented in the first config, if --ignore-config is present in the first config. This is the responsibility of the user, if he wants to use config files.
