Fun fact: debug information is actually an array of structures. Historically,
YARA has stopped parsing after finding the first entry with a PDB path (with
some other restrictions around the type of debug entry this is). However, each
entry can have different information (including pdb paths), so let's add an
array of debug_infos structures which contain timestamp, type and pdb path.

Just in testing I discovered legit binaries that have different PDB paths in
them, which is actually kind of interesting.

Specifically, I'm only parsing out the timestamp field of the structure.

While here, rename the newly created "debug_infos" array to "debug_details".
