Write each trace only on time in HeaderLine

Merge pull request equinor#319 from jokva/seismic-unix-support

Seismic unix support

1.7.1

* Fixed an issue where writing traces on memory-mapped files was a no-op
* Depth slices dimensions are always in fast-by-slow
* catb/catr has some new output formats
* Some docs entries updated and fixed

Version 1.7.0

* segyio has learned to open non-ascii file paths on Windows
* Fixed an issue where segyio-catr would sometimes print the same trace twice
* segyio no longer incorrectly considers files where the
  inline/crossline/offset triple doesn't change sorted
* The test suite has seen some overhaul, making test cases more focused on the
  actual thing to test
* Checking sorting won't silently fail when the offset-word is broken
* `f.text` is now a Sequence, meaning it has slicing and other common array
  operations
* The makefiles no longer build both static and shared libraries, but rather
  respect the BUILD_SHARED_LIBS variable
* Python 3.7 support
* Various refactoring and internal improvements

Version 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

Version 1.5.3

* segyio-catr has learned to handle no arguments, and as a results read the
  first trace header as intended
* segyio-catr has its help text and man page corrected
* segyio-crop has learned to say how many traces it copies
* segyio-crop has learned to warn when no traces are copied
* segyio-crop has learned not to overwrite its input file when source and dest
  is the same
* The makefiles understand the BUILD_DOC option, to build the python docs with
  sphinx
* Test suite has some speed and robustness improvements
