xarray_to_cdf is creating corrupt cdf files when reading in FILLVAL attributes as strings.
This issue arose when writing code for the IMAP mission--particularly the IDEX instrument. FILLVAL was written as -1.0E+31 rather than -1.0e+31, and xarray_to_cdf did not raise an error. Rather, the function load_cdf in imap_processing.utils.py caught the issue giving a ValueError that "the buffer is smaller than the requested size."
