AttributeError: module 'eccodes' has no attribute 'codes_grib_multi_support_reset_file' after the 0.9.9.0 release

Hi there,

Worked fine on 0.9.8.5 version, however started throwing an AttributeError on the 0.9.9.0 one.
As an example:
cfgrib.open_dataset(file_path, backend_kwargs={"filter_by_keys": {"numberOfPoints": 2556, "typeOfLevel": "hybrid", "edition": 2, "level": 128}})

Can't create file 'INDEX_FILE.idx'
Traceback (most recent call last):
  File "../python/lib/python3.7/site-packages/cfgrib/messages.py", line 344, in from_indexpath_or_filestream
    self = cls.from_filestream(filestream, index_keys)
  File "../python/lib/python3.7/site-packages/cfgrib/messages.py", line 293, in from_filestream
    for message in filestream:
  File "../python/lib/python3.7/site-packages/cfgrib/messages.py", line 229, in __iter__
    with multi_enabled(file):
  File "../python/lib/python3.7/contextlib.py", line 112, in __enter__
    return next(self.gen)
  File "../python/lib/python3.7/site-packages/cfgrib/messages.py", line 51, in multi_enabled
    eccodes.codes_grib_multi_support_reset_file(file)
AttributeError: module 'eccodes' has no attribute 'codes_grib_multi_support_reset_file'
Can't read index file 'INDEX_FILE.idx'
Traceback (most recent call last):
  File "../python/lib/python3.7/site-packages/cfgrib/messages.py", line 353, in from_indexpath_or_filestream
    index_mtime = os.path.getmtime(indexpath)
  File "../python/lib/python3.7/genericpath.py", line 55, in getmtime
    return os.stat(filename).st_mtime
FileNotFoundError: [Errno 2] No such file or directory: 'INDEX_FILE.idx'

Any idea on what might be the cause of that?

The latest version of cfgrib is compatible only with fairly new version of the eccodes python package, but I failed to add this minimum version in the setup.py. I'll add it and make a new release.

As a work-around you need to update the package with ecCodes python bindings depending on you install setup. This is different for pip, conda and other installation strategies.

Thanks for the report.

I also have this question :
ds = xr.open_dataset("C:\\Users\\liuc\\Downloads\\era5-levels-members.grib", engine="cfgrib")

W:\software\anaconda\lib\site-packages\cfgrib\messages.py in multi_enabled(file)
