* add utility method for generating npos inputs
* add a fuzzer which asserts that all unbalanced seq_phragmen are PJR
Note that this currently fails. I hope that this can be rectified
by calculating the threshold instead of choosing some arbitrary number.
* assert in all cases, not just debug
* leverage a native solution to choose candidates
* use existing helper methods
* add pjr-check and incorporate into the fuzzer
We should probably have one of the W3F people look at this to ensure
we're not misconstruing any definitions, but this seems like a
fairly straightforward implementation.
* fix compilation errors
* Enable manually setting iteration parameters in single run.
This gives us the ability to reproducably extract cases where
honggfuzz has discovered a panic. For example:
$ cargo run --release --bin phragmen_pjr -- --candidates 569 --voters 100

thread 'main' panicked at 'unbalanced sequential phragmen must satisfy PJR', primitives/npos-elections/fuzzer/src/phragmen_pjr.rs:133:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
This is still not adequate proof that seq_phragmen is broken; it could
very well be that our PJR checker is doing the wrong thing, or we've
somehow missed a parameter of interest. Still, it's concerning.
* update comment verbiage for accuracy
* it is valid in PJR for an elected candidate to have 0 support
* Fix phragmen_pjr fuzzer
It turns out that the fundamental problem causing previous implementations
of the fuzzer to fail wasn't in `seq_phragmen` _or_ in `pjr_check`: it was
in the rounding errors introduced in the various conversions between the
internal data representation and the external one.
Fixing the fuzzer is then simply an issue of using the internal representation
and staying in that representation. However, that leaves the issue that
`seq_phragmen` occasionally produces an output which is technically not
PJR due to rounding errors. In the future we will need to add some kind of
"close-enough" threshold. However, that is explicitly out of scope of
this PR.
* restart ci; it appears to be stalled
* use necessary import for no-std
* use a more realistic distribution of voters and candidates
This isn't ideal; more realistic numbers would be about twice these.
However, either case generation or voting has nonlinear execution
time, and doubling these values brings iteration time from ~20s to
~180s. Fuzzing 6x as fast should make up for fuzzing cases half the size.
* identify specifically which PJR check may fail
* move candidate collection comment into correct place
* standard_threshold: use a calculation method which cannot overflow
* Apply suggestions from code review (update comments)

This edge count is used for weighing, and it is somewhat trivial to review and verify that the current implementation was ignoring `votes16` field of the struct. As reminder, the struct is like this:
```rust
struct Compact {
votes1: ... ,
votes2: ...,
...,
votes16: ...,
}
```
I already will fix this in https://github.com/paritytech/substrate/pull/7007, but since it might take a while, this one can go in asap and make it to the very next runtime.

This removes the `dev-dependency` onto `sp-npos-elections` from itself.
A crate should not depend on itself directly, especially not to make any
macros work.
