read_bundle_element → read_bundle_element_content

Thanks to @glindstedt for mentioning this inconsistency.

Previously there was `read_bundle_element` and
`read_bundle_element_size` where the first one was confusing since a
bundle element consists of its size and contents but the method only
read the contents.
