Forbid `len(...) > 0` expressions

Rule request

Thesis

We all know that if len(x) > 0 is an anti-pattern.
It should be replaced with if x or if not x: for if len(x) == 0 or if len(x) <= 0

So, the rule is when we find len(...) and its compare with zero or >= 1, then we raise a violation.

Reasoning

That's simply not pythonic, it is also shorter to write correctly.
