  Create a compressor object for compressing data incrementally.
  
  format specifies the container format to use for the output. This can
  be FORMAT_XZ (default), FORMAT_ALONE, or FORMAT_RAW.
  
  check specifies the integrity check to use. For FORMAT_XZ, the default
  is CHECK_CRC64. FORMAT_ALONE and FORMAT_RAW do not suport integrity
  checks; for these formats, check must be omitted, or be CHECK_NONE.
  
  The settings used by the compressor can be specified either as a
  preset compression level (with the 'preset' argument), or in detail
  as a custom filter chain (with the 'filters' argument). For FORMAT_XZ
  and FORMAT_ALONE, the default is to use the PRESET_DEFAULT preset
  level. For FORMAT_RAW, the caller must always specify a filter chain;
  the raw compressor does not support preset compression levels.
  
  preset (if provided) should be an integer in the range 0-9, optionally
  OR-ed with the constant PRESET_EXTREME.
  
  filters (if provided) should be a sequence of dicts. Each dict should
  have an entry for "id" indicating the ID of the filter, plus
  additional entries for options to the filter.
  
  For one-shot compression, use the compress() function instead.
