---------------------------------------------------------
I worked on this a bitt, adding a {{ seek(byte_offset) }} and {{ get_block() }}
method to the _CompressedFile class (see
[commit|https://github.com/tim1357/incubator-beam/commit/891bf0a6f064698422a7612c04659e8ac2b2494d]).

> Make BZIP compressed files splittable

> Bzip2 is compressed as blocks, so it should be possible to do dynamic
> splitting. To do this: Seek to a location in the bzip, then keep seeking
> until you find the 6 byte block-start sequence 0x314159265359 (which is the
> 12 digit approximation of pi). You can use a bzip2 decompressor from that
> point onwards.
