py-soupsieve: updated to 1.9.0

1.9.0:
NEW: Allow :contains() to accept a list of text to search for.
NEW: Add new escape function for escaping CSS identifiers.
NEW: Deprecate comments and icomments functions in the API to ensure Soup Sieve \ 
focuses only in CSS selectors. comments and icomments will most likely be \ 
removed in 2.0.
NEW: Add Python 3.8 support.
FIX: Don't install test files when installing the soupsieve package.
FIX: Improve efficiency of :contains() comparison.
FIX: Null characters should translate to the Unicode REPLACEMENT CHARACTER \ 
(U+FFFD) according to the specification. This applies to CSS escaped NULL \ 
characters as well.
FIX: Escaped EOF should translate to U+FFFD outside of CSS strings. In a string, \ 
they should just be ignored, but as there is no case where we could resolve such \ 
a string and still have a valid selector, string handling remains the same.
