Handy slice 🍕 functions using go generics

## Usage

```go

import "github.com/iancanderson/cowabunga"

ints := []int{1, 2, 3}

allAreBig := All(ints, func(n int) bool { return n > 2 })

// false

anyAreBig := Any(ints, func(n int) bool { return n > 2 })

// true

numBig := Count(ints, func(n int) bool { return n > 2 })

// 1

lastTwo := Drop(ints, 1)

// [2, 3]

lastOne := DropWhile(ints, func(n int) bool { return n < 3 })

// [3]

EachCons(ints, 2, func(nums []int) {

	fmt.Println(nums)

})

// [1, 2]

// [2, 3]

EachSlice(ints, 2, func(nums []int) {

	fmt.Println(nums)

})

// [1, 2]

// [3]

sum := 0

sum = EachWith(ints, &sum, func(num int, result *int) {

	*result += n

})

// 6

bigNumbers := Filter(ints, func(n int) bool { return n > 2 })

// [3]

bigNumbersIncremented := FilterMap(ints, func(n int) *string {

	if n > 2 {

		str := strconv.Itoa(n + 1)

		return &str

	} else {

		return nil

	}

})

// ["4"]

firstGreaterThanOne := Find(ints, func(n int) bool { return n > 1 })

// [&2]

firstNum := First(ints)

// 1

strings := FlatMap(ints, func(n int) string {

	return []string{strconv.Itoa(n), strconv.Itoa(n + 1)}

})

// ["1", "2", "2", "3", "3", "4"]

byEven := GroupBy(ints, func(n int) bool { return n % 2 == 0 })

// map[true:[]int{2} false:[]int{1, 3}]

hasATwo := IsMember(ints, 2)

// true

lastNum := Last(ints)

// 3

strings := Map(ints, func(n int) string { return strconv.Itoa(n + 1) })

// ["2", "3", "4"]

firstTwo := Take(ints, 2)

// [1, 2]
