   I receive the same error when reading a zstd compressed feather file. According to the Apache Arrow documentation, in V2, compression is supported. However, the following command
   ```
   Python 3.8.3 (default, Jul  2 2020, 11:26:31) 
   [Clang 10.0.0 ] :: Anaconda, Inc. on darwin
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import pyarrow.feather as feather
   >>> feather.read_feather("data/IPTC_subject_codes_test.feather.zst", compression="zstd")
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
   TypeError: read_feather() got an unexpected keyword argument 'compression'
   >>> feather.read_feather("data/IPTC_subject_codes_test.feather.zst")
   Traceback (most recent call last):

     File "/Users/home/.local/share/virtualenvs/RD17147-yQ3Y_lVD/lib/python3.8/site-packages/pyarrow/feather.py", line 231, in read_feather
       return (read_table(
     File "/Users/home/.local/share/virtualenvs/RD17147-yQ3Y_lVD/lib/python3.8/site-packages/pyarrow/feather.py", line 256, in read_table
       reader = _feather.FeatherReader(
     File "pyarrow/_feather.pyx", line 79, in pyarrow._feather.FeatherReader.__cinit__
     File "pyarrow/error.pxi", line 144, in pyarrow.lib.pyarrow_internal_check_status
     File "pyarrow/error.pxi", line 100, in pyarrow.lib.check_status
   pyarrow.lib.ArrowInvalid: Not a Feather V1 or Arrow IPC file
   ```
   I can read an uncompressed file but I would like to take advantage of compression.
   The version of pyarrow I have is 11.0.0
