fix: reflective dunder methods operation order

The reflective dunder methods are called when the normal dunder fails.
This normally does not matter for commutative operations, like addition,
but for division and subtraction, this can lead to errors.

For example,
  def  __sub__(self, other)
is meant to solve `self - other`
while
  def __rsub__(self, other)
is meant to solve `other - self`

The following reflective dunder methods were fixed to honor
the correct direction of operations:
   __rsub__
   __rfloordiv__
   __rtruediv__
   __rmod__
   __rpow__
