Feature request: Allow sorting of frequency distribution

In the frequency distribution, the results are sorted by input byte. Sometimes for frequency analysis it's more useful to sort by frequency ascending/descending, but it's not trivial to do the sort with CyberChef as it is because the percentages are factional.

It would be good if there was an option (like filter blanks) that added support to sort the frequency in ascending (or descending) order.

Start by locating the frequency distribution operation and how its results are currently ordered and displayed. Add an option for ascending or descending frequency order, then verify that fractional percentages sort numerically and that the existing input-byte order remains available.
