According to the PDF doc, an entry in the document's name dictionary,
listing the JavaScript actions, is required to execute parameterized
function call.
Also note that:

In this case, the name is _0000000000_.
After investigating an odd error:
# NotImplementedError: unsupported filter /Fl
I saw the PDF had this line:
# <</Filter/Fl/First 12/Length 828/N 2/Type/ObjStm>>stream
But most objects had:
# <</Size 306/Filter/FlateDecode/Length 947/Type/XRef/W[1 3 1]
After looking at the filters.py file, I saw the short-names were not added. After modifying the filters.py, the code is up and running again.
A thanks to Matthew Weiss for helping with this as well.
Each "TJ" entry is a separate piece of text so provide some way for the user to separate them in the extracted text. This way the user can then txt.split("\n") to get a list of all text blocks
