mismatch in parameter to vary station tag fontsize and its docstring, in recsec

I was trying to increase the `fontsize` of the station tags in my record sections. There seems to be a mismatch between the variable `y_label_fontsize` and its docstring `ylabel_fontsize` in `recsec`. I was trying to use `ylabel_fontsize` as mentioned in the documentation, but looking at the source code I had to use `y_label_fontsize`, which worked. It will be helpful to sort this out.
