sample_indices: update model parameters

This accounts for the "cache" method being replaced by
rejection sampling and now using usize again.

sample_indices: use f32 in heuristics and add short-cut
...
Motivation: don't have to worry about overflow whichever index type is used.
Appears to slightly improve some benchmarks, no affect on others.

sample_indices: update selection heuristics
...
Update with new benchmark data from `u32` impls of Floyd's and cached
algorithms (inplace alg already used benchmarks from `u32` impl).
Update Floyd's with a balanced model adequate for both shuffled
and unshuffled versions.
