Support for different file types

[thisisparker]

Puzzle parsing and state is pretty abstracted from the file format except during loading and saving — it would likely be possible to allow cursewords to open jpz and ipuz files, given the right library support.

I'd really love to see .ipuz support, and would be interested in helping out where needed.

I think this library should be helpful: https://github.com/svisser/ipuz (docs)

I would love it if cursewords supported the across lite text format as well as the .puz format. The txt format is simple and sometimes I parse a puzzle and create the text format rather than the .puz file. I can use across to convert my text files to puz and use them in cursewords, but it kind of defeats the purpose. The text format is documented here: https://www.litsoft.com/across/docs/AcrossTextFormat.pdf

Or I have attached a file:
test_puz.txt
