Add option for fuzzer to toggle DAA

Of note, this is a breaking change to the fuzzed format
for any canvas fuzzers.  I've updated the seed corpora to match
but any repro cases predating this will need to have the a single
byte added to the front of the test case:

echo -n -e '\x00' | cat - file > outputfile
