Cannot write cell value using numpy
*Created originally on Bitbucket by [CoryKramer (Cory Kramer)](https://bitbucket.org/%7Bb770e48f-bd38-468d-8272-9cf6671cbd8f%7D/)* The following code works without issue ``` #!python import openpyxl workbook = openpyxl.Workbook() sheet = workbook.create_sheet('Test') sheet.cell(row=1, column=1).value = 1.0 ``` However the following version of this code causes an error ``` #!python import numpy import openpyxl workbook = openpyxl.Workbook() sheet = workbook.create_sheet('Test') a = numpy.array([1.0]) sheet.cell(row=1, column=1).value = a[0] ``` In the latter case, the `value` being assigned is of type `numpy.float64`. In the `Cell._bind_value` method, this type is not considered to be `NUMERIC_TYPES` so therefore causes a `ValueError` at the end of the method.
