`v0.8.1`

Added a .exactly_one() iterator method that, on success, extracts the single value of an iterator ; by @Xaeroxe
- Added combinatory iterator adaptors:
  - .permutations(k):
    
    [0, 1, 2].iter().permutations(2) yields
```
[
  vec![0, 1],
  vec![0, 2],
  vec![1, 0],
  vec![1, 2],
  vec![2, 0],
  vec![2, 1],
]
```
    ; by @tobz1000
  - .combinations_with_replacement(k):
    
    [0, 1, 2].iter().combinations_with_replacement(2) yields
```
[
  vec![0, 0],
  vec![0, 1],
  vec![0, 2],
  vec![1, 1],
  vec![1, 2],
  vec![2, 2],
]
```
    ; by @tommilligan
  - For reference, these methods join the already existing .combinations(k):
    
    [0, 1, 2].iter().combinations(2) yields
```
[
  vec![0, 1],
  vec![0, 2],
  vec![1, 2],
]
```
- Improved the performance of .fold()-based internal iteration for the .intersperse() iterator ; by @jswrenn
- Added .dedup_by(), .merge_by() and .kmerge_by() adaptors that work like .dedup(), .merge() and .kmerge(), but taking an additional custom comparison closure parameter. ; by @phimuemue
- Improved the performance of .all_equal() ; by @fyrchik
- Loosened the bounds on .partition_map() to take just a FnMut closure rather than a Fn closure, and made its implementation use internal iteration for better performance ; by @danielhenrymantilla
- Added convenience methods to EitherOrBoth elements yielded from the .zip_longest() iterator adaptor ; by @Avi-D-coder
- Added .sum1() and .product1() iterator methods that respectively try to return the sum and the product of the elements of an iterator when it is not empty, otherwise they return None ; by @Emerentius

`v0.8.0`
