8241037690 factor::miller_rabin: Extract dividers from the primality test 
Another 36% improvement.

6b9585b1dc factor::miller_rabbin: Refactor before extracting dividers 
Replace iterated division with u64::trailing_zeros, hoist the selection of `mul`
out of the loop, another cool 49.5% runtime improvement.

169740629b factor::table: Remove extraneous calls to the primality test 
50% performance improvement on factoring all numbers between 2 and 10⁶.

418fd61759 factor::factor: Short-circuit the fallback to Pollard's rho 
When the remainder is smaller than the max. entry in the table,
it is guaranteed to be prime.

bc11e57962 factor::factor: Use u64::trailing_zero instead of iterated division 
No significant performance impact (most of the time is spent elsewhere),
but an easy and satisfying fix nevertheless.

a1b2522750 factor: Move each factorisation method to its own module 
Also decoupled the factorisation methods; now factor::factor contains
the logic that chains the different algorithms and aggregates results.

As a side-effect, rho::factor now performs extraneous allocations (as each
recursive step creates a new `Factors` value, which is then aggregated into
the previous one) but there is no significant performance impact.

d9095a2539 factor: Refactor (eheh) around a Factors datatype 
It is clearer to see what is going on, as opposed to passing around an
unmarked `Vec<u64>`, and there is a single place to add invariants checks.

This is also a more compact memory representation: each prime factor is
represented only once, with an additional byte for multiplicity.  The
performance impact is however not significant.

71ba8b3fd6 sort: add "dictionary-order" flag. 
The flag makes 'sort' command ignore non-dictionary symbols
(non-alphanumeric and non-spaces). The only difference with GNU sort is
that it takes ALL alphanumeric symbols, not only ASCII ones.
