Consolidate LengthOf classes

[neonailol]

As the title says, why there are multiple LengthOf classes when one of the points of elegant objects is to provide rich constructors for the object? Each current implementation of LengthOf can be merged into a single class, and I don't see why it should not be that way.

@neonailol where would we put this LengthOf?

[neonailol]

@llorllale all of the implementations are NumberEnvelope so probably it belongs to scalar, but I think numbers should be in their own package

[llorllale]

@neonailol agreed

Bug was reported, see §29: +15 point(s) just awarded to @neonailol/z

[llorllale]

@neonailol FYI, when I agreed here I meant it probably should belong to org.cactoos.scalar, not to create a new package for numbers.

[neonailol]

@llorllale I am ok with that
