Fixed issues with the formatting. It looks like the CI tests are failing because of a compilation issue:

error[E0432]: unresolved import `alloy_sol_types`
 --> crates/signer/src/signer.rs:8:5
  |
8 | use alloy_sol_types::{Eip712Domain, SolStruct};
  |     ^^^^^^^^^^^^^^^ use of undeclared crate or module `alloy_sol_types`

I don't believe I made any changes that caused this. Anything I need to should be doing to fix this @DaniPopes?
