So turns out genPOI wants to use sorted() so it can use itertools.groupby.
Python 2 somehow just... sorted objects so that groupby (which is basically
the UNIX uniq) could group them properly. Python 3 no longer does this,
so as comparison method let's just compare regiondir strings since that
gives us the desired result.
Fixes#1597.
Apparently not even chunks of that data version can be relied upon
to have that flag mean anything at all, as the --forceUpgrade and
--eraseCache switches result in a world where chunks are flagged
as not being lit but seemingly do have SkyLight and BlockLight keys.
Concerns #1570.
Minecraft notes various stages of fetal development that chunks are
in, with the complete ones being "full". Previously, we'd check
against a list of states that are not full to skip a chunk, which
is obviously not future proof, and broke as Mojang updated their
possible range of values for the status field. It's better to
just bail if the status is anything other than "full".
Additionally, a key called "isLightOn" is in the chunk now. This
seemingly determines whether a chunk has been lit. We're also going
to check for this, and bail if it's not. In my tests, I have not yet
seen a single "full" chunk that does not have "isLightOn" set.
Fixes#1558.
This is a new directory added in 1.14 which contains .mca files too.
Since we scan for directories with .mca files to use as RegionSets,
and we don't know how to handle these, just skip them.
Fixes some warnings during rendering.
Sorry for the noise in mc_id.h, but somebody decided they want DOS
line endings and I couldn't allow that to happen. When not doing that
put the whole thing into diff, I decided to just fix the indentation
too while I was at it.
Needed bugfixing of some overlooked unsigned char usages for block IDs,
as otherwise the lighting would be scuffed.

Inner/outer corners apparently have their data from ancil data instead
of Minecraft's stuff, so we might need to fix that in the future.
Many things work, some don't. Notably, genPOI doesn't work, and
there's some signedness comparison stuff going on in the C extension.
This also completely drops support for Python 2, as maintaining a C
extension for both Python 2 and 3 is a pain and not worth it for the
9 months that Python 2 is still going to be supported upstream.
The documentation needs to be adjusted as well.
All of the few tests we have pass, and rendering a map works, both
with a configuration file and without. We can also use optimizeimages.
Concerns #1528.
