chore: bump version

In PHP 8.1 floats are not implicitly converted to integers as before. 
The array_slice on line 139 requires an integer as the third parameter (the $count variable) so added line 117 to do the conversion of $count.

+Lorem ipsum generator in PHP without dependencies. Compatible with PHP 5.3+.
-well as HHVM.
-
-## Origins
-
-Once upon a time, I was attempting to find a lorem ipsum generator over on
-[Packagist](https://packagist.org/search/?q=lorem%20ipsum). I was presented
-with many options, and some of those options were good. Unfortunately, the
-bulk of those options depended on Symphony or the Zend Framework. This
-wouldn’t have been a big deal but under the circumstances, I wanted something
-that was not tightly coupled to these frameworks because I wanted to use the
-generator in my _own_ framework.
-
-I had decided to use
-[badcow/lorem-ipsum](https://packagist.org/packages/badcow/lorem-ipsum)
-because it did not have any dependencies nor did it rely on any external APIs.
-As I started to use the library, I found that I was going to have to fight
-with it to get it to do what I wanted. After digging through the code, I
-realized that I was going to end up gutting most of it to bend it to my will.
-I know when you overhaul someone’s code the liklihood of them accepting a pull
-request goes down dramatically, hence building this library while taking cues
-from it’s predecessor.
-
-Also, the aforementioned package had a bunch of “setter” and “getter” methods
-that were grossing me out :scream:
