Mostly NFC; this commit is mainly to get familiar with the codebase and to meet
the people who will review these changes.
I hope to make some changes to the DAN parsing code to eventually extract more
metainfo from my aqualung divecomputer's `.zxu` formatted logs. To do so, and
for me to be able to work on this efficiently, I've refactored the DAN parsing
code using a bit more modern C++-style, as well as being more true-to-spec wrt.
the (...ancient) DAN file format documentation that i could dig up... hopefully
that's an alright tradeoff for the project.
This more true-to-spec parsing also fixed a bug with the number being parsed
from the incorrect index in the ZDH vector (or, atleast i consider it a bug -
the "Export sequence" number was being used as the dive number, instead of the
"Internal Dive Sequence" number. The latter, described in the spec as: `The
sequence number assigned to the dive by the recording computer`).
Also contains some unrelated formatting changes; i tried to keep these minimal
(i presume these files haven't been touched in a while by `clang-format`).
