Fix import for multipletests from statsmodels for 0.15.0

[colleenjg]

Summary

receptive_field.py is incompatible with the latest version of statsmodels (0.15.0), as the following import now fails:

from statsmodels.sandbox.stats.multicomp import multipletests

This is because multipletests, which is defined in statsmodels.stats.multitest, is no longer globally imported in statsmodels.sandbox.stats.multicomp.

This commit fixes the import, and is fully backward compatible as multipletests has been defined in statsmodels.stats.multitest since around version 0.4.x, around 14 years ago.
