**Changes:**
- Add support for Gaussian PSF (see 2).
- Rename function `hash_` to `hashfunc` to remove conflicts with variables names `hash_` in the code.
For user code, add a compatibility function `hash_` that raises a `FutureWarning`.
- Fix previously ignored `chunkslice` argument. This argument is either `'time'` or `'bytes'` and determines
if `chunksize` refers to the number of elements or bytes.
- Code and docstrings cleanups.
