Previously, reading fragment 512 would panic with index out of range.
Fix that panic by introducing an abstraction over reading blocks of
items, caching the intermediate result, and returning an item at a
particular index. The primary goal of this abstraction is to make edge
cases like requesting items on page boundaries easy to unit test for.
Additionally, fix unit tests by making t.Fatal calls protected by
nil checks on the error values.
This library is a lower level version of the main squashfs library that doesn't try to be easy to use and exposes a lot of information that is not necesary for must use cases.
