Avoid using enif_inspect_iolist_as_binary in NIFs #113

iolist_to_iovec before the NIF call, then enif_inspect_iovec in the NIF is what we recommend these days

It’s not quite as convenient as enif_inspect_iolist_as_binary but it’s not too awful, and it’s generally faster since it doesn’t copy any data unless it absolutely has to
We do use it currently a short grep delivered:
yrael:grisp peer$ grep -r enif_inspect_iolist .
