Configure and disable word wrap in console reporter

Right now the console reporter hard-codes the column width to 80 (default determined by Clara):

```cpp
void printMessage() const {
if (!messageLabel.empty())
stream << messageLabel << ':' << '\n';
for (auto const& msg : messages) {
// If this assertion is a warning ignore any INFO messages
if (printInfoMessages || msg.type != ResultWas::Info)
stream << Column(msg.message).indent(2) << '\n';
}
}
```

I'd like for each message to be printed with a custom column width, or no column width (disable word wrap). Is there a mechanism to do this right now? If not, what would be the best way to configure this? Looking for an ideal design approach and am happy to implement it.

@philsquared Please advise on your ideal design, I don't want to waste effort on a PR if I don't do things how you prefer them to be. Thanks.

Start by locating the console reporter's printMessage implementation and the Column type used in the shown snippet. Check whether existing reporter configuration or command-line options already control formatting; done means establishing a maintainer-approved design for custom or disabled wrapping and covering the resulting behavior with tests.
