Error where truncation can occurr and prevent truncation in the future
by using `type::from()` (which checks for truncation) instead of `as
type` (which doesn’t).
The reason for the switch is mostly related to error handling (and me
being unable to unterstand how nom does it). Using byteorder and a few
handwritten helper functions for parsing makes error handling much
easier. It also allows me to return more helpful error messages.
