Making these functions static makes it easier to implement lazy-loading
since the parsing functions can now be called at any time.
The functions were reorganized because they were not defined in the
order they are called. However, instead of moving every function to
that order, I've declared some but defined them further into the file,
which allows the next commit's diff to be more readable.
Matroska::Reader functions now return DecoderErrorOr instead of values
being declared Optional. Useful errors can be handled by the users of
the parser, similarly to the VP9 decoder. A lot of the error checking
in the reader is a lot cleaner thanks to this change, since all reads
can be range checked in Streamer::read_octet() now.
Most functions for the Streamer class are now also out-of-line in
Reader.cpp now instead of residing in the header.
As new demuxers are added, this will get quite full of files, so it'll
be good to have a separate folder for these.
To avoid too many chained namespaces, the Containers subdirectory is
not also a namespace, but the Matroska folder is for the sake of
separating the multiple classes for parsed information entering the
Video namespace.
