* src/factor.c: Add --exponents option for printing in x^y format.

Thanks for the suggestion.
This is one of those borderline cases.
Mainly because it's fairly easy to postprocess the output.
Consider for example:
$ factor 13 36 | tr ' ' '\n' | uniq -c
1 13:
1 13
1 36:
2 2
2 3
Though for interactive use, the new option is a benefit.
Given the interactive benefit and a previous request to add this functionality¹
I'm tentatively leaning towards adding this.
cheers,
