py-html-sanitizer: updated to 1.6.1

1.6:
Fixed another edge case where a tag which is allowed to be empty was erroneously \ 
removed if it contained not only whitespace but also a <br> tag.

1.5:
Fixed a few edge whitespace normalization edge cases and a bug where removing an \ 
empty tag removed all whitespace.
Added black for automatically formatting the Python code.
By default, links with target="_blank" get an additional \ 
rel="noopener" attribute (Article by Mathias Bynens). If you're \ 
overriding the list of allowed attributes for anchor tags you must add rel to \ 
your list.

Log message:
Add py-html-sanitizer-1.3.0:

html-sanitizer is a whitelist-based and very opinionated HTML sanitizer
that can be used both for untrusted and trusted sources. It attempts to
clean up the mess made by various rich text editors and or copy-pasting
to make styling of webpages simpler and more consistent. It builds on the
excellent HTML cleaner in lxml to make the result both valid and safe.

It goes further than pure tag filtering by transforming the HTML
fragments to normalize formatting and drop redundant or pointless tags.
