`@CONTROL{REVTEX41Control}` statement ignored
The [AIP LaTeX template](https://www.overleaf.com/latex/templates/template-for-submission-to-aip-publishing-journals/xhsskcchtbxf) produces an extra bib file, typically named `articleNotes.bib` (when the main tex file is `article.tex`). It contains the following two lines:

```bibtex
@CONTROL{REVTEX41Control}
@CONTROL{aip41Control,pages="1",title="0"}
```

The first line seems to be ignored by python-bibtexparser, while `bibtex` can properly handle it.

Minimal example to reproduce the issue:

```python
import bibtexparser
btp = bibtexparser.bparser.BibTexParser(ignore_nonstandard_types=False)
print(bibtexparser.load(open("articleNotes.bib"), btp).entries)
```

This only prints out the entry corresponding to the second control line:

```python
[{'title': '0', 'pages': '1', 'ENTRYTYPE': 'control', 'ID': 'aip41Control'}]
```
