Unsupported parameter in pandas read_excel

[petercoles]

The chapter 2 01_build_itch_order_book notebook, attempts to read message type definitions from an xlsx file using Pandas read_excel method.

One of the parameters passed is the file's encoding. However the current version of pandas doesn't support the encoding argument, causing it to throw an error.

Happily simply removing the parameter allows the file to be loaded without problem, though I don't know if there might be backwards compatibility issues for people running older versions of Pandas.
