Fill NaN values by propogating values backward

Requires bottleneck.

Parameters:
dim : str

Specifies the dimension along which to propagate values when filling.

limit : int, default None

The maximum number of consecutive NaN values to backward fill. In other words, if there is a gap with more than this number of consecutive NaNs, it will only be partially filled. Must be greater than 0 or None for no limit.
