Arm9 bootloader v0.4.1 Alpha

This is a arm9 bootloader, which is based on bootctr. It allows the users to use the old boot_config.ini, without the need to modify it.
You can use the standalone version, through building arm9loaderhax in this repository and reinstall it, or you could use the arm9loaderhax.bin included in his release to use it with any brahma payload launcher(like Cakebrah or arm9loaderhax). For the full usage guide checkout the Readme

With this release I added the possibility to configure the brightness used for screeninit. To configure it set "screenBrightness" inside of the "BOOTCTR9" section to a value between 0x0 and 0xFF.
