Version 0.30.4

[xloem]

Hi,

I'm new to go, but it looks like lotus 1.11.0 (commit 283793f9435b12be03e0de43ac017eba3dc1ceac tag v1.11.0) refers to filecoin-ffi 0.30.4:

https://github.com/filecoin-project/lotus/blob/v1.11.0/go.mod#L29

github.com/filecoin-project/filecoin-ffi v0.30.4-0.20200910194244-f640612a1a1f

Should the version in this repository be bumped from 0.30.3?
