Description
Currently:
julia> @MMatrix I(3)
ERROR: LoadError: @MMatrix only supports the zeros(), ones(), fill(), rand(), randn(), and randexp() functions.
It would be nice to support @MMatrix I(n) for quick and efficient construction of statically sized identity matrix (and similarly for @SMatrix)

Research direction
Start by locating the @MMatrix and @SMatrix macro entry points and reproduce the reported Julia example. Trace how supported constructors such as zeros() are handled, then verify that I(n) constructs statically sized identity matrices for both macros without the current error.
