BUG: Add delimiters to NameObject.renumber_table

[ztravis]

Per the spec, name objects cannot contain unescaped delimiters, which include angle, curly and square brackets (currently missing).

I've attached a sample input PDF with a valid, correctly escaped name object. When appending this to a new PdfWriter the output is invalid (incorrectly escaped):

>>> w = PdfWriter()
>>> w.append('nameobj.pdf')
>>> w.write('out.pdf')

out.pdf
nameobj.pdf

Thanks for the PR. Could you please indicate which section of the PDF reference you are referring to here?

Do you see any benefits of building a test based on this?

[ztravis]

In the PDF reference version 1.7 name objects are defined in section 3.2.4, which states:

The name may include any regular characters, but not delimiter or
white-space characters (see Section 3.1, “Lexical Conventions”).

Section 3.1 defines delimiter characters:

The delimiter characters (, ), <, >, [, ], {, }, /, and % are special.

I just added a test, yes!
