Projectkk2glider/flash savings (#4199)

* Flash savings: getFileExtension() de-templated, saves 160 bytes * Flash savings: several variables moved to rodata, RGB macro optimization (speed and can now be used to initialize rodata) Result for Horus: text data bss dec 1261182 808603 42020 2111805 before 1267149 803335 42124 2112608 after (data size also counts .sram section) 5kB saved in .data section (RAM and FLASH) * Removed compiler warnings * RGB() and ARGB() gtests added * ARGB() optimized
