Reporting of Test

**Describe the bug**
I catched a bug in my code by some test, but the error message was a little misleading:
```
FAILED:
[ctest] CHECK_THAT( some_uint8_t, WithinAbs(5.5, 0.5) )
[ctest] with expansion:
[ctest] '2' is within 0.5 of 5.5
```

I wondered, where the 2 could have possibly come from, until I ran the test in the VSCode debugger, which automatically prints next to each uint8_t variable its numeric value and it's ascii character.

'2' is a character, but we're doing a number comparison, so printing a character is only misleading.

**Expected behavior**
```
FAILED:
[ctest] CHECK_THAT( some_uint8_t, WithinAbs(5.5, 0.5) )
[ctest] with expansion:
[ctest] 50 is within 0.5 of 5.5
```

**Reproduction steps**
Something like
```
#include
#include
TEST("misleading error message", "") {
uint8_t var = 50;
CHECK_THAT( var, WithinAbs(5.5, 0.5) );
}
```
