Exit Flow atrous rate in XCeption backbone

[babanthierry94]

Please,
Why are you using exit_block_rates = (1, 2) in the backbone construction ?
I could not see it the the original paper. In the original paper for OS=16 I think all Sep Conv rate are 1.

Please can you help me understand your choice.
