0xb3 is the generic error code (or success, where applicable). Let's handle
those by default so that the rest of the messages only have to care about
replies with message-specific opcodes.

0xc3 is 'download the oldest file'
0xca is 'delete the oldest file' (usually the one we just received) from the tablet.
0xc1 is 'how many files are there'

Some raw log files may be empty if we cancelled tuhi at the wrong time. Skip
over those while testing

This is a slightly different model as the messages, primarily because it's not
quite as model-specific. So there's only one parse function and it can handle
both file types that we currently support (intuos pro and the spark/slate
bits).
All wrapped into their own classes to make future extensions a bit easier.
It's not a 1:1 implementation of the tuhi/wacom.py bits either because we now
know about a few extra bits like the flags in stroke headers.
Most importantly though, this can be easily tested now, with one test case
searching for raw logs in $XDG_DATA_HOME/tuhi/raw and parsing all of those. So
the more files are sitting in there (i.e. the more the tablet is used), the
better the test suite becomes.

The dimensions of the tablet are in device units, the point size tells us how
big the actual tablet is.

A few messages where we assumed the argument is a single byte are actually
little-endian 16 bits. let's add easy-to-use wrappers.
