ValueError: cannot specify integer bins when input data contains infinity [BUG]

[flppgg]

Trying to open a dataframe from a .csv that contains numpy.inf values fails with this error:

import lux, pandas
df = pandas.read_csv('filepath')

simply setting
pandas.set_option('mode.use_inf_as_na', True)
solves the issue for the user, but I don't know how this can be solved in lux

Thanks @flppgg! It looks like this issue comes up when we try to plot a binned histogram when the data contains inf. We'll look into fixing this issue!
