Projectkk2glider/flash savings (#4199)

Browse Source 
* 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
