Version 1.8.0

1.8.0

• segyio has learned the seismic unix file format, and can read and write SU
  files. This feature is found in the segyio.su module
• segyio supports least-significant-byte (LSB/little-endian) first formatted
  files
• Fixed a bug that caused writing headers in non-linear mode very slow,
  and wrong under some conditions
• segyio also considers files with descending line/offset numbers sorted, not
  just ascending
• The python file handle has learned the interpret method, which allows
  specifying structure directly, rather than inferring it from file metadata.
  This is particularly useful for files with structure, but broken headers
• A new family of from_array functions are added to the tools module,
  intended for quick-and-easy storing a 2/3/4D volume on disk
• Sorting defaults to inline in segyio.create if nothing is specified
• Text.__setitem__ used a wrong variable and didn't really work, but is now
  fixed
• Internal imports are tidied up
• The test suite in both Python and C++ have seen some minor improvements
• An experimental C++ interface is available for source builds, but is not
  considered stable - internals and interface can change with no prior notice.
  The experimental interface is enabled when segyio is built with
  -DEXPERIMENTAL=ON
