Issues decompressing bytes from files

[brendanofallon]

This is probably user error, but I'm running into an issue compressing a file on the command line and decompressing it inside python. For example:

$ blpk --version                                                            
bloscpack: '0.16.0' python-blosc: '1.10.2' blosc: '1.21.0'

$ blpk compress foo.csv foo.csv.blp

$ ipython
 In [1]: import blosc
 In [2]: blosc.__version__
 Out[2]: '1.10.2'
 In [3]: blosc.decompress(open('foo.csv.blp', 'rb').read())
 ...
 error: Error 39148941 : not a Blosc buffer or header info is corrupted

The file decompresses just fine using blpk on the command line, but doesn't seem to work using python-blosc for some reason. When saving compressed data from within python, I am able to decompress it without issue, but something about the format of the command-line produced data seems to cause an issue with decompression. Similar code works fine with other compression utilities like gzip and lz4

This is related to bloscpack package, not this one. In case this is still an issue, please open a ticket there.
