py-soupsieve: updated to 1.9.1

1.9.1
- **FIX**: :root, :contains(), :default, :indeterminate, :lang(), and :dir() \ 
will properly account for HTML
iframe elements in their logic when selecting or matching an element. Their \ 
logic will be restricted to the document
for which the element under consideration applies.
- **FIX**: HTML pseudo-classes will check that all key elements checked are in \ 
the XHTML namespace (HTML parsers that do
not provide namespaces will assume the XHTML namespace).
- **FIX**: Ensure that all pseudo-class names are case insensitive and allow CSS \ 
escapes.
