Fixes #553.
Now, the token is generated deterministically and thus the
dak_cacheis hit correctly for multiple repetitive invocations ofdak.map_partitionswith the same arguments.Unfortunately I couldn't use
__dask_tokenize__because one needs to repack theargsandkwargscorrectly.Not sure how much of a performance gain there is, would be nice to measure it somehow...
