  Fix pdal metadata test on old-ish osx (#1718)

Utils::from_string for pointers falls prey to a libc++ bug (19740) on
old-ish osx clang. Because `operator>>(istream, void*&)` uses `sscanf`
under the hood, there *shouldn't* be any issues with using `sscanf`
instead of `operator>>` for this function in order to work around the
bug.
