Print relative paths instead of absolute path

**Description**
The console output for catch2 is really messy with absolute paths.
An option to get the path printed as relative path would be amazing!

**Additional context**
Current output
```
/home/nandanv/code/sources/.../test/src/sensors/test_temperatureSensor.cpp:99
```
I suggest
```
test/src/sensors/test_temperatureSensor.cpp:99
```
The user may specify what portion of the path should be truncated if required. I think doxygen does something similar.
