0d39732300 factor::Decomposition: Inline a small number (4) of factors
This avoids allocating on the heap when factoring most numbers,
without using much space on the stack.

This is ~3.5% faster than the previous commit, and ~8.3% faster than “master”.

b7b0c76b8e factor::Decomposition: Optimise as a factor is never added twice
The invariant is checked by a debug_assert!, and follows from the previous
commit, as `dec` and `factors` only ever contains coprime numbers:
  - true at the start: factor = ∅ and dec = { n¹ } ;
  - on every loop iteration, we pull out an element `f` from `dec` and either:
    - discover it is prime, and add it to `factors` ;
    - split it into a number of coprime factors, that get reinserted into `dec`;
      the invariant is maintained, as all divisors of `f` are coprime with all
      numbers in `dec` and `factors` (as `f` itself is coprime with them.

As we only add elements to `Decomposition` objects that are coprime with the
existing ones, they are distinct.

b8ef58c002 factor::Factors: Split off a Decomposition type
The new type can be used to represent in-progress factorisations,
which contain non-prime factors.

6158cd5714 factor: Introduce a type alias for exponents
This way, we can easily replace u8 with a larger type when moving to support
larger integers.

sort: fix panic on write to closed pipe

sort: fix panic on write to closed pipe
If the output of sort is piped to another program that closes the file
descriptor, sort currently panics. The GNU coreutils is able to handle
this case.

Replacing panic with crash_if_err reports the closed pipe and exits
with a return code, which seems like the correct behavior. Tested on
my Mac and the panic disappears.

Add a test which pipes data to sort - it won't protect against this
specific regression, but it increases the test coverage, at least.

Fixes #1608.
