#### `UNITY_INCLUDE_PRINT_FORMATTED`
Unity provides a simple (and very basic) printf-like string output implementation,
which is able to print a string modified by the following format string modifiers:
- __%d__ - signed value (decimal)
- __%i__ - same as __%i__
- __%u__ - unsigned value (decimal)
- __%f__ - float/Double (if float support is activated)
- __%g__ - same as __%f__
- __%b__ - binary prefixed with "0b"
- __%x__ - hexadecimal (upper case) prefixed with "0x"
- __%X__ - same as __%x__
- __%p__ - pointer (same as __%x__ or __%X__)
- __%c__ - a single character
- __%s__ - a string (e.g. "string")
- __%%__ - The "%" symbol (escaped)
_Example:_
```C
#define UNITY_INCLUDE_PRINT_FORMATTED
int a = 0xfab1;
UnityPrintFormatted("Decimal %d\n", -7);
UnityPrintFormatted("Unsigned %u\n", 987);
UnityPrintFormatted("Float %f\n", 3.1415926535897932384);
UnityPrintFormatted("Binary %b\n", 0xA);
UnityPrintFormatted("Hex %X\n", 0xFAB);
UnityPrintFormatted("Pointer %p\n", &a);
UnityPrintFormatted("Character %c\n", 'F');
UnityPrintFormatted("String %s\n", "My string");
UnityPrintFormatted("Percent %%\n");
UnityPrintFormatted("Color Red \033[41mFAIL\033[00m\n");
UnityPrintFormatted("\n");
UnityPrintFormatted("Multiple (%d) (%i) (%u) (%x)\n", -100, 0, 200, 0x12345);
