Support the implementation of FADC and SCTNet

[qiuyuan666]

Is there anyone who can implement the FADC and SCTNet network codes in mmsegmentation? Many thanks to everyone who has contributed to this. The relevant papers and code repositories for these two networks are as follows:

(1)FADC:
Code: https://github.com/Linwei-Chen/FADC

(2)SCTNet:
Paper: https://arxiv.org/pdf/[2312.17071](https://arxiv.org/pdf/2312.17071)
Code: https://github.com/xzz777/SCTNet
