feature request: control output format of source location based on compiler used

Currently, in HRF format, the source location is printed as `file.ext(lineno):`.
For example

```
./.././detail/test.cpp(764): error in "test_name": check a == b has failed [3 != 6]
```

It would be good for automated tools to have the alternative to print the source location in format more similar to source locations printed in clang and gcc (also Catch2), i.e. `file.ext:lineno`.
For example the modified format out would print:

```
./.././detail/test.cpp:764: error in "test_name": check a == b has failed [3 != 6]
```

**Would it be possible to add this options to the format output?**

(I tried editing the strings in `/usr/include/boost/test/minimal.hpp` and in `test/impl/compiler_log_formatter.ipp:print_prefix` but that didn't do it.)
