Changes in version 4.0

To better partition cell styles, background image data which was supported in earlier versions through the methods image_data and image_filename is now part of the new cell_style property. Using the deprecated methods image_data and image_filename will issue a DeprecationWarning if used.The legacy methods will be removed in a future version of numbers-parser.

NumberCell cell values limited to 15 significant figures to match the implementation of floating point numbers in Apple Numbers. For example, the value 1234567890123456 is rounded to 1234567890123460 in the same way as in Numbers. Previously, using native float with no checking resulted in rounding errors in unpacking internal numbers. Attempting to write a number with too many significant digits results in a RuntimeWarning.

The previously deprecated methods Document.sheets() and `Sheet.tables() are now only available using the properties of the same name (see examples in this README).
