New package, p5-Calc-Math-Units. From Alberto Mijares via wip, though I fixed
some typos.

From DESCR:
Math::Calc::Units is a simple calculator that keeps track of units. It
currently handles combinations of byte sizes and duration only, although
adding any other multiplicative types is easy. Any unknown type is
treated as a unique user type (with some effort to map English plurals
to their singular forms).
