<data>
This section doesn't seem to carry any payload data except dll names.
- typelib section format:
<section header>
<module names[]>
<index[]>
<data[]> --- <data>
<helpstring>
Header is fixed length, index is an array of fixed length 'struct guid_index'.
All strings are WCHAR, null terminated, 4-bytes aligned. Module names part is
4-bytes aligned as a whole.
Module name offsets are relative to section, helpstring offset is relative to data
structure itself.
