p5-Digest-SHA3: update to 0.27.

0.27  Wed Oct  4 00:40:04 MST 2017
	- removed "portable" mode from sha3sum and addfile
		-- rarely used, mostly in outdated systems
		-- potentially confusing features (e.g. \r\r\n -> \n)
		-- Universal Newlines mode (-U) a much cleaner approach
			-- mimics Universal Newlines in Python
	- sha3sum now depends explicitly on Digest::SHA3
		-- eliminates runtime loading of modules
		-- no future plans to write Digest::SHA3::PurePerl
