Need to manually translate row_half from human-readable form in YAML
(top/bottom) to true/false. Requesting a Node as a uint8_t returns the
first char in the YAML field rather than parsing the field as an
integer. Just used unsigned ints and let the constructor force them to
smaller types.

Type 0 shouldn't exist but bitstreams generated with
BITSTREAM.GENERAL.DEBUGBITSTREAM=YES seem to use them as padding.

binary literals are a C++14 feature. Use hex literals instead to
keep C++11 compatibility.

Type 2 packets are used for when the amount of data required exceeds the
word count field in a Type 1 header. ConfigurationPacket mostly hides
this detail from the user but occasionally it is handy for debugging.

Both ConfigurationPacket and Configuration need to reference registers.
Use a common scoped enum to reduce change of errors. Leverage stream
operator to simplify outputing register names.

Class names were getting unwieldy. Use a namespace to group all the
7series classes and allow for shorter class names.

Acts as an iterator that yields a single record from the file. Uses a

mmap() will fail for a zero-length mapping. A valid object should still
be returned to signal that the file was opened to the caller but it
should have a nullptr for data and zero for size.
