Summary

Format import statements in all their variants. Specifically, this implemented formatting StmtImport, StmtImportFrom and Alias.

Test Plan

I added some custom snapshots, even though this has been covered well by black's tests.

i was surprised there wasn't a blanket Option<T>: T: AsFormat impl for .format()

[MichaReiser]

I think I ran into issues when I tried adding it last time because Rust doesn't know that T doesn't implement Format and AsFormat at the same time
