Fixes #156
Adds new test cases for encode and decode of unpaired surrogates (Note: I've only run the tests in nodejs thus far).
Fixes
utf8ToBytes()behaviour to match that ofBuffer.from(string), i.e. to encode unmatched surrogates as U+FFFD, and thus the behaviour is now the same for strings <64 and >64 in length.I didn't make any changes to the decode behaviour because that seems good already (it performs U+FFFD substitution).
