Title: Fix parsing dimensions in xlsx files

Note that this pull request is missing tests, but I want first to check that my approach is fine. The problem is that some xlsx files have the following start:

```

```

note that dimension is "1:49", while xlrd expects it to be of the form "A1:D49".

In my patch I add an argument for cell_name_to_rowx_colx, which allows parsing cell names with missing columns, and if we have no information about column range in this file, we just do not set them.

If this is fine, I will add direct tests for cell_name_to_rowx_colx (currently, there are no such direct tests).
