Version 1.6.0

1.6.0

• segyio has learned to handle int16 and int32 sample formats
• segyio has learned to write any array_likes with any float-convertible
  contents. f.trace = np.linspace(0, 1, 0.01) works as expected.
• segyio types have been extended to be more container-like, and conform to
  more protocols. Notably, headers and lines are properly dict_like, and traces
  are properly array_like
• trace.ref added, a write-back mode where changes to yielded trace data are
  written back to disk
• trace.raw has been improved, is faster and supports setitem and the
  container protocol
• Headers have learned to accept (seismic unix) keywords in update, so
  header.update(cdpx=10) works as expected
• f.dtype added, this is the dtype used in all segyio-provided numpy arrays,
  and reflects the underlying data format
• f.readonly added, to query if file handles are writable
• segyio gracefully handle non-contiguous and more array_likes in setitem
• The type requirements of f.samples has been relaxed, and it now is whatever
  numpy uses as default
• segyio now assumes IBM float if the format identifier is meaningless
• Some exception types are cleaned up, notably header key misses raise
  KeyError, not IndexError
• General speed and clarity improvements, some more exception guarantees
• segyio has learned to raise an error when provided with too short data traces
• segyio has started raising deprecation warnings when using to-be-removed
  features
• The python library has overall been simplified
• Lots of new documentation has been written, the sphinx docs structure has
  been overhauled
