feat: add slice method to array/fixed-endian-factory

lib/node_modules/@stdlib/array/fixed-endian-factory/README.md

@@ -837,6 +837,73 @@ 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 which shares an [`ArrayBuffer`][@stdlib/array/buffer] with the target array, the method will intelligently copy the source range to the destination range.

+
+#### TypedArrayFE.prototype.slice( \[start\[, end]] )
+
+Copies a portion of a typed array to a new typed array.
+
+```javascript
+var Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
+// returns <Float64ArrayFE>
+
+var out = arr.slice();
+// returns <Float64ArrayFE>
+
+var len = out.length;
+// returns 5
+
+var v = out.get( 0 );
+// returns 1.0
+
+v = out.get( len-1 );
+// returns 5.0
+```
+
+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 Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
+// returns <Float64ArrayFE>
+
+var out = arr.slice( 1 );
+// returns <Float64ArrayFE>
+
+var len = out.length;
+// returns 4
+
+var v = out.get( 0 );
+// returns 2.0
+
+v = out.get( len-1 );
+// returns 5.0
+```
+
+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 Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
+// returns <Float64ArrayFE>
+
+var out = arr.slice( 1, -2 );
+// returns <Float64ArrayFE>
+
+var len = out.length;
+// returns 2
+
+var v = out.get( 0 );
+// returns 2.0
+
+v = out.get( len-1 );
+// returns 3.0
+```
