Spitfire Patcher

This is a custom patcher for applying modifications to firefox source code. It processes patch files located in the `./patches` directory and applies them to files in a specified root path.

## How to Use 1. Place your patch files in the `./patches` directory. Example of patch file: ```patch --- /browser/branding/official/configure.sh +++ /browser/branding/official/configure.sh -MOZ_APP_DISPLAYNAME=Firefox +MOZ_APP_DISPLAYNAME=Spitfire ``` 2. Run the patcher with the `--path` flag: ```sh go run patch.go --path=./mozilla-central ``` *Root path will be resolved to an absolute path, and patches will be applied relative to this path.*
