Support for pandas.read_* and DataFrame.to_* functions

[xjcl]

First of all, thanks for your project.

I was wondering if support for pandas I/O (https://pandas.pydata.org/docs/user_guide/io.html) was possible to add and in scope for this package. Their I/O functions also have an encoding= argument:

• Reader functions like pandas.read_excel, pandas.read_csv
• Writer functions like pandas.DataFrame.to_excel, pandas.DataFrame.to_csv

I am not really sure how to do this. Maybe it would even be better to check in general if any function you call has an encoding= keyword argument, or would that be likely to produce false positives?
