parser crash with a tag without href

htmldocx 0.0.6
An a tag without href causes the following error:

File "/home/victor/Proyectos/html2docx/./prueba.py", line 36, in
new_parser.add_html_to_document(txt2, document)
File "/home/victor/Proyectos/html2docx/venv/lib/python3.10/site-packages/htmldocx/h2d.py", line 591, in add_html_to_document

self.handle_link(link['href'], data)
KeyError: 'href''

My suggestion is:
add
if 'href' in link:
in line 514

the patch could be:
line 512:
link = self.tags.get('a')
if link:
if 'href' in link:
self.handle_link(link['href'], data)
else:
