[Feature Request] `greaterThanOrEqual` and `lessThanOrEqual`

[schnittstabil]

What

greaterThan(), lessThan() and between are great, but these doesn't always feel right:

// value >= 0
$v->required('value')->greaterThan(-1);          // integer only
$v->required('value')->between(0, PHP_INT_MAX);  // integer only(?)
$v->required('value')->between(0, INF);          // float only(?)

// value <= 0
$v->required('value')->lessThan(1);              // integer only
$v->required('value')->between(PHP_INT_MIN, 0);  // integer only(?)
$v->required('value')->between(-INF, 0);         // float only(?)

What is expected

greaterThanOrEqual and lessThanOrEqual rules:

$v->required('value')->greaterThanOrEqual(0);
$v->required('value')->lessThanOrEqual(0);

Hi @schnittstabil, thank you for your suggestion! The thing for Particle\Validator, is that we want to keep the library as small as possible, but we want to provide the most used validation rules. So I understand how adding these functions can make your code more explicit/logical, but do we really want to add these since the functionality is more or less the same? What do you think?

To be honest, I don't know if ->between(0, PHP_INT_MAX) and ->between(0, INF) have any drawbacks. As PHP_INT_MAX depends on the platform and INF is a double, it is at least not obvious to me that these work on all edge cases.

OBTW, I intended create a PR – of course, only if this feature is welcome.
