Thanks for your work on quiffen.

I have a qif file from a Quicken export with a security that is not publicly traded, so it has a name and no symbol.

That produces an error with from Qif.parse using quiffen 2.0.13, shown below.

$ ./example.py
Traceback (most recent call last):
  File ".../example.py", line 6, in <module>
    qif = Qif.parse('ex.QIF', day_first=False)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File ".../.venv/lib/python3.12/site-packages/quiffen/core/qif.py", line 249, in parse
    raise ParserException(
quiffen.core.qif.ParserException: Line 2: No symbol found for security.

Here is an ex.QIF:

^
!Type:Security
NExample
TStock

In my local copy, I used the name as the symbol with the following patch:

$ diff -p .venv/lib/python3.12/site-packages/quiffen/core/security.py tmp/security.py

          if line_number is not None:
              kwargs["line_number"] = line_number
  
+         # if symbol is not present, use the name
+         kwargs["symbol"] = kwargs.get("symbol", kwargs.get("name"))
+ 
          return cls(**kwargs)
  
      @classmethod

I'd be happy to submit that as a PR if you wish.
