Description of proposed changes
This PR adds the support of reading
int8type for files in GDAL format, as suggested by @scottstanie in #1081.add the correction
int8conversion between GDAL and NumPy inDATA_TYPE_GDAL2NUMPY/NUMPY2GDALadd
numpy_to_gdal_dtype()fromdolphinadd
gdal_to_numpy_dtype()fromdolphinI did not replace the usage of dict conversion with the two functions above yet, because
cint16/32is supported by GDAL but not in numpy yet, thus, the dict conversion may be more generic at the moment for translation purposes.Reminders
