parseJSON for the variations on ISO-8601 dates as listed in ECMA-262.
toJSON for ZonedTime limits the milliseconds to three digits
Added eitherDecode and eitherDecode'
They are just like decode and decode' respectively
but return an error message when decoding fails.
Fix #72.

Sometimes, it appears, Nullary constructors can be encoded as Null as
well as an empty array [not sure why one this!]. The Generic code, as of
49befcafc80a85b371a6e0e0d5ab4ad9b33d8778, fails when a Null is
passed for a nullary constructor. Add in a pattern match to fix this
issue.
