snowball release

Snowball has made a release!  With a tag!

I have prepared a patch to update PostgreSQL's copy.  (not attached 
here, 566230 bytes, but see 
https://github.com/petere/postgresql/commit/52a6133b58c77ada4210a96e5155cbe4da5e5583)

Since we last updated our copy from their commit date 2019-06-24 and the 
release is from 2019-10-02, the changes are pretty small and mostly 
reformatting.  But there are three new stemmers: Basque, Catalan, Hindi.

I think some consideration could be given for including this into PG13. 
Otherwise, I'll park it for PG14.
