Add compression and chunksize keyword argument to HDF5Sink

Summary

Currently, the HDF5Sink does not support a chunksize and compression argument.

The proposal would be to define the chunksize as an int, which specifies the size of the chunk in the savefile along the first dimension.

For the compression argument, a tuple could be used, e.g. ('gzip', 1).

What is the current workaround to achieve the same functionality?

No.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
