At present text entries use an indirect method to specify the text to use,
with a label pointing to the text itself.
Allow the text to be directly written into the node. This is more
convenient in cases where the text is constant.

This code reads a binary value and then uses it as a string to look up
another value. Add conversions to make this work as expected on Python 3.

It is not good practice to raise an exception in a constructor. In this
case the 'text' entry may not actually be used, if -i is used to filter
out the images that get built.
Move the exception to where the data is actually used.

When the value of a text entry is not provided an execption is generated
talking about a None type. This is confusing. Add a more explanatory error
and a test for this case.

At present only the more complex entries are documented. It is useful to
have documentation for all entries in one place.
As a first step, add and expand the documentation to cover all entries.

It is useful to able to write an identifying string to the image within an
entry. Add a 'text' entry type to handle this. The actual text is
typically passed to binman on the command line. The text is not itself
nul-terminated but this can be achieved if required by setting the size of
the entry to something larger than the text.
