Disable Brotli Compression by John Galt

Disables Brotli compression by removing "br" from the Accept-Encoding HTTP request header. The remaining available encodings are "gzip", "deflate", and "zstd". This ensures that the server uses one of these encodings, which offer better compression and significantly faster decompression.

Some proxy users also experience difficulties because their proxy servers do not support Brotli. This extension fixes that problem as well.
