Make enums

[gorkemcaylak]

It is better practice to have these defined as enums in the header file similar to this:

enum Commands {
CHECK_STATUS = 0,
TAKE_PICTURE = 1,
...
}

soci_cdh_rtos/cdh_prototype/wrappers/imag_wrap.h

Lines 10 to 20 in 71131db

	/* Commands that can be tested */
	static const unit8_t CHECK_STATUS = 0x00;
	static const unit8_t TAKE_PICTURE = 0x01;
	static const unit8_t GET_THUMBNAIL_SIZE = 0x02;
	static const unit8_t GET_PICTURE_SIZE = 0x03;
	static const unit8_t GET_THUMBNAIL = 0x04;
	static const unit8_t GET_PICTURE = 0x05;

	static const unit8_t SET_BRIGTHNESS = 0x07;
	static const unit8_t SET_EXPOSURE = 0x08;
