libpressio version 0.18.0

libpressio version 0.18.0

Major Features

• Libpressio now has basic HDF5 file support.
• Breaking change: previously pressio_features() returned only a list
  of compressors that are supported. This doesn't make sense according
  to its name. With the addition of HDF5 support, there are now optional
  features that require additional dependencies that are not compressors.
  Therefore, the old functionality of pressio_features() has been moved
  to pressio_supported_compressors(), and pressio_features() has been
  re-specified to include the new functionality.

Bug Fixes

• Minor improvements to documentation
