Motivation

Hello, I made some small modifications to ddrnet in my own experiments and later wanted to inference these models in the model hardware library (https://platform.openmmlab.com/deploee/), so I submit this PR. Thank you so much.

This is my first time to submit PR, please forgive me if there is any problem, and I will revise it as soon as possible.

Modification

The CBAM module is mainly added to the residual module corresponding to ddrnet model, the common convolution is changed to packet convolution, and the FAPPM module is created by combining PAPPM and DAPPM modules.
Those new config files are the combination of these improvements. These combinations are only personal experiments and may not work for every task, but they worked in my experiment.
