the configuration of ZFP was changed in order to be able to run the ZFP 
automatic test suite.
Apparently, the test code assumes `BIT_STREAM_WORD_TYPE=uint64` (see 
also [1]).
If I revert the change I will need to disable many the ZFP tests.
Apparently the problem seems to be linked to specific testing code bot 
on the ZFP and the python-hdf5plugin side.
Honestly I cannot say what is the more appropriate configuration for 
`BIT_STREAM_WORD_TYPE`.

How do you propose to proceed?
