⬆️ Bump rasterio from 1.0.13 to 1.0.16

[dependabot-preview]

Bumps rasterio from 1.0.13 to 1.0.16.

Changelog

Sourced from rasterio's changelog.

1.0.16 (2019-02-04)

• A bug preventing GCPs from being created with new BufferedDatasetWriter
  instances (#1600) has been fixed (#1610).
• A previously unreported bug preventing BufferedDatasetWriters from being
  opened in r+ mode has been fixed.
• A regression in creating CRS objects from PROJ4 strings that include
  "+wktext" (#1609) has been fixed.
• Regressions in str representations of empty CRS objects and the handling of
  unreferenced datasets in rasterio._base have been fixed (#1616).
• GDAL seems to work best if GDAL_DATA is set as early as possible. Ideally it
  is set when building the library or in the environment before importing
  Rasterio, but for wheels we patch GDAL_DATA into os.environ when rasterio.env
  is imported. This resolves #1611.

1.0.15 (2019-01-27)

• Google cloud storage support was not in fact added in 1.0.14, but is
  present in 1.0.15.

1.0.14 (2019-01-22)

• The _CRS class has been refactored so that a WKT representation, rather than
  PROJ4 representation, is the canonical form. This resolves issues #1397 and
  #1587 specifically, and an entire category of issues discussed in
  https://rasterio.groups.io/g/dev/message/68.
• Native support for Google Cloud Storage using "gs://" URLs has been added
  (#1577).
• On entering a dataset context (DatasetBase.enter) a new anonymous GDAL
  environment is created if needed and is entered. This makes with rasterio.open(...) as dataset: roughly equivalent to with rasterio.open(...) as dataset, Env():. This helps prevent bugs when datasets
  are created and then used later or are used in different scopes.
