Support modifying cells

[chrisspen]

The docs imply that this package can only read an ODS file into a Python dictionary or write a Python dictionary to an ODS file. This destroys all data in the ODS file that doesn't have a Python equivalent, such as formatting and formulas. It would be convenient to be able to modify an ODS file in place, such as modifying only certain cells in the file.

Thanks for your interest in pyexcle-ods. I am afraid I am going to reject your issue. The reason are:

1. The goal of pyexcel is mainly to extract data from and store data back into excel formats, including ODS.
2. pyexcel-ods reply on odfpy for reading ODS. Hence, you would be advised to try with odfpy.

I have reserved the consideration to support some styles but have no plan to read the styles, formats and put the same back into the same file.
