GetVarInt() returns uint32_t. So assign the results to variables of type
uint32_t. Then make sure those results get passed on as uint32_t, or use
pdfium::base::IsValueInRangeForNumericType<T>() to make sure they can be
converted to type T safely.

Sample PDF:
https://yadi.sk/d/oWLtAEfy3YbEb3
For offsets, equal to the hint stream offset, added hint stream
length to determine the actual offset, because linearization
inserted the hint stream at the original location of the object.
Also the number of bits needed to represent the numerator of
the fractional position for each shared object reference may be
zero, if each shared group contains only one object with obj num,
incremented on 1.
