Replaced "Word/Word8.fromInt <int literal>" with "0w" word literals wherever possible.
- Replaced deprecated fromLargeWord and toLarge with fromLarge and toLarge
- Renamed variables formerly named "from" to "src" since "from" is a keyword in AliceML.
- Added type annotation where type of word literal is ambiguous between Word.word and Word8.word.
Disambiguated Word8.word literals by using word8 function, which converts Word.word into Word8.word.
Renamed pack and unpack function to doPack and doUnpack since they are keywords in AliceML.
