Fix #3833. Among the options for chart axes in Excel are the ability to show labels as multiples of specific powers of 10, with or without an explanatory label. The Excel spec seems to indicate that that you can customize the multiples to other values, but I don't see how to do that in Excel, so that can be a project for another day if someone figures out how. The label title can also be styled; that is not part of this PR, but I will look into it in future. For now, this PR supports the use of multiples with or without labels. The axes can also be displayed on a logarithmic scale (any base between 2 and 1000). This PR supports that.
