Data.Text.Encoding.Base16.decodeBase16Lenient fails in base16-1.0 with `Invalid UTF-8 stream`

[jonathangenlambda]

Data.Text.Encoding.Base16.decodeBase16Lenient fails in base16-1.0 with Invalid UTF-8 stream:

"\NUL\DC4ß\DLEGENS" `shouldBe` Data.Text.Encoding.Base16.decodeBase16Lenient "0014df1047454e53"

fails with

uncaught exception: UnicodeException
       Cannot decode byte '\xdf': Data.Text.Encoding: Invalid UTF-8 stream

This is a regression as with base16-0.3.2.1 this didn't fail and produced the string "\NUL\DC4ß\DLEGENS"

Also the haddock clearly states that decodeBase16Lenient never fails: using a strategy that never fails, catching unicode exceptions raised in the process.

Thanks for the report @jonathangenlambda.

I have some homework to do now. None of that code significantly changed in this library between 1.0 and 0.3.2.1, so my suspicion is that the minimum dependency bumps are to blame here. I'm working on bisecting.
