feat: add slice and subarray methods to array/bool

lib/node_modules/@stdlib/array/bool/README.md

@@ -865,6 +865,82 @@ A few notes:
 -   If a target array cannot accommodate all values (i.e., the length of source array plus `i` exceeds the target array length), the method throws an error.
 -   If provided a [typed array][@stdlib/array/typed] which shares an [`ArrayBuffer`][@stdlib/array/buffer] with the target array, the method will intelligently copy the source range to the destination range.

+#### BooleanArray.prototype.slice( \[start\[, end]] )
+
+Copies a portion of a typed array to a new typed array.
+
+```javascript
+var arr = new BooleanArray( 5 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( true, 2 );
+arr.set( false, 3 );
+arr.set( true, 4 );
+
+var out = arr.slice();
+// returns <BooleanArray>
+
+var len = out.length;
+// returns 5
+
+var bool = out.get( 0 );
+// returns true
+
+bool = out.get( len-1 );
+// returns true
+```
+
+By default, the method returns a typed array beginning with the first array element. To specify an alternative array index at which to begin, provide a `start` index (inclusive).
+
+```javascript
+var arr = new BooleanArray( 5 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( true, 2 );
+arr.set( false, 3 );
+arr.set( true, 4 );
+
+var out = arr.slice( 1 );
+// returns <BooleanArray>
+
+var len = out.length;
+// returns 4
+
+var bool = out.get( 0 );
+// returns false
+
+bool = out.get( len-1 );
+// returns true
+```
+
+By default, the method returns a typed array which includes all array elements after `start`. To limit the number of array elements after `start`, provide an `end` index (exclusive).
+
+```javascript
+var arr = new BooleanArray( 5 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( true, 2 );
+arr.set( false, 3 );
+arr.set( true, 4 );
+
+var out = arr.slice( 1, -2 );
+// returns <BooleanArray>
+
+var len = out.length;
+// returns 2
+
+var bool = out.get( 0 );
+// returns false
+
+bool = out.get( len-1 );
+// returns true

+Creates a new typed array view over the same underlying [`ArrayBuffer`][@stdlib/array/buffer] and with the same underlying data type as the host array.

+var arr = new BooleanArray( 5 );

+var bool = subarr.get( 0 );
+// returns false
+
+bool = subarr.get( len-1 );
+// returns true
+```
+
 #### BooleanArray.prototype.toReversed()
 
 Returns a new typed array containing the elements in reversed order.
