They can be used to read integral values from a range of ubytes. You can use
either std.file.read or std.stdio.File to read from the file and than those
functions from std.bitmanip to convert the ubytes to integrals.
std.file.read would be the easiest to use, since it just gives you a single
dynamic array to deal with, but it does mean reading in the entire file at
once.
