When test binaries are run with unknown options or with the standard
-h option, a help menu will print all available options.
This is much more convenient than having to dig through unity.c to
find every option.
This change helps Unity parse and print correctly in cases where a long
or long long type is passed to TEST_PRINTF.
Example situations:
```C
// With %u:
TEST_PRINTF("%u %d\n", ((1ULL << 63) - 1), 5); // --> prints 11982546 -1 (both arguments incorrect because only 4 of the 8 bytes were read out of the va_list)
// With %llu, UNITY_SUPPORT_64=0
TEST_PRINTF("%llu %d\n", ((1ULL << 63) - 1), 5); // --> prints 4294967295 5 (first argument wrapped, second argument intact)
// With %llu, UNITY_SUPPORT_64=1
TEST_PRINTF("%llu %d\n", ((1ULL << 63) - 1), 5); // --> prints 9223372036854775807 5 (both arguments correct)
```
Compiling a source base / test with Wswitch-enum enabled, gives
the following warning:
../src/unity.c: In function ‘UnityAssertFloatSpecial’:
../src/unity.c:1092:5: warning: enumeration value ‘UNITY_FLOAT_INVALID_TRAIT’ not handled in switch [-Wswitch-enum]
1092 | switch (style)
| ^~~~~~
Fix by adding the missing value to the default (unhandled) case.

Depends on UnityPrintFormatted (define UNITY_INCLUDE_PRINT_FORMATTED).
UnityPrintFormatted has been renamed to UnityPrintF due to changes below.
API of UnityPrintFormatted has been changed (hence the rename), but end users
(developers) can use the TEST_PRINTF as an almost-drop-in replacement TEST_PRINTF
is compatible with the old UnityPrintFormatted API (see below).
The behaviour of UnityPrintF has also been changed:
- Now it prefixes the outout with test location information Output is marked
as INFO.
- It adds an EOL.
Both behaviours adopted from other output functions.
By passing --omit_begin_end=1 to generate_test_runner.rb, the script
will now omit calls to UnityBegin and UnityEnd when running tests in a
suite.
This allows multiple suites to be executed in a row, and then have an overall
summary of the tests which were executed across all suites.
