TimeoutException: fix defaults to avoid notices with PHP 8.1

[Thomas-Gelf]

When being strict about deprecations, once reaching a timeout(), your code will fail on PHP 8.1. That's what this pull request attempts to fix.

Hint: created two distinct commits, the first one allows to trigger the error. You can have a look at a failing test run here.

@Thomas-Gelf Thanks for looking into this, your changes make a lot of sense to me! I've filed #49 a few days ago which adds documentation for the existing APIs and also stumbled upon this.

As a first step, I think adding the documentation for the existing API via #49 makes sense. Accordingly, the message can be given as a null value to the constructor (not suggesting it's a good idea, merely inspecting the existing API). As such, I think we should probably apply your changes to address the default type, but also type cast internally in case a null value is given explicitly.

What do you think about this?

Hi @clue,

I love the improvements in #49. It's easier to read and to understand, and the type hints are very helpful. I adjusted the pull request to keep the method signature as is.

@Thomas-Gelf Awesome, thank you for the update, changes LGTM!

Keep it up 👍
