Center alignment for fmt
Use '^' to specify center alignment in format strings.
fmt!( "[{:^5s}]", "Hi" ) -> "[ Hi ]"
fmt!( "[{:^5s}]", "H" ) -> "[ H ]"
fmt!( "[{:^5d}]", 1i ) -> "[ 1 ]"
fmt!( "[{:^5d}]", -1i ) -> "[ -1 ]"
fmt!( "[{:^6d}]", 1i ) -> "[ 1 ]"
fmt!( "[{:^6d}]", -1i ) -> "[ -1 ]"
If the padding is odd then the padding on the right will be one
character longer than the padding on the left.
