There is no API for providing **kwargs to Compressor.decompress

[braingram]

As discussed here:
braingram/asdf-compression#1 (comment)

Compressor.decompress accept **kwargs:

asdf/asdf/extension/_compressor.py

Line 63 in ecb4d4f

def decompress(self, data, out, **kwargs):

These are provided during compression.decompress (passed in from the config argument):

asdf/asdf/compression.py

Line 273 in ecb4d4f

len_decoded = decoder.decompress(blocks, out=buffer.data, **config)

However config is not defined during block decompression:

asdf/asdf/_block/io.py

Line 150 in ecb4d4f

data = mcompression.decompress(fd, used_size, header["data_size"], compression)

To propose a possible solution (to start the conversation) it might be possible to specify decompression_kwargs either per-block or per-codec/label. Something like the following:

asdf.open('test.asdf', decompression_kwargs={0: {...}, 'lz4': {...}, ...})
