feat: new unique features asConstArray asImmutableArray

[RodrigoDornelles]

• const ability to create an array of constant size in which elements cannot be subtracted or added.
• immutable ability to create an array so that the data is not mutable once added.

<?php

class ArrayConst implements ArrayAccess {
    private $data = [];

    public function offsetExists($offset) {
        return isset($this->data[$offset]);
    }

    public function offsetGet($offset) {
        return $this->data[$offset] ?? null;
    }

    public function offsetSet($offset, $value) {
        if ($offset === null) {
            $this->data[] = $value;
        } else if (!isset($this->data[$offset])) {
            $this->data[$offset] = $value;
        }
    }
    
    public function __debugInfo() {
    	return $this->data;
    }
    
    public function offsetUnset($offset) {
    	
    }
}

$arr = new ArrayConst();
$arr['foo'] = 'bar';
$arr['foo'] = 'bar2';
print_r($arr);

mayable:

$arr = ArrayLib::from(['foo', 'bar', 'z'])
   ->setExcepetions(false)
   ->setImmutable(true)
   ->setConst(true)
   ->asArray();
   
$arr[2] = 'y';
$arr[3] = 'x';
 
echo json_encode($arr); // prints: ['foo', 'bar', 'z']
