py-Unidecode: update to 1.0.22.

2018-01-05	unidecode 1.0.22
	* Move to semantic version numbering, no longer following version
	  numbers from the original Perl module. This fixes an issue with
	  setuptools (>= 8) and others expecting major.minor.patch format.
	  (https://github.com/avian2/unidecode/issues/13)
	* Add transliterations for currency signs U+20B0 through U+20BF
	  (thanks to Mike Swanson)
	* Surround transliterations of vulgar fractions with spaces to avoid
	  incorrect combinations with adjacent numerals
	  (thanks to Jeffrey Gerard)
