Consider using `thiserror` instead of `anyhow` in `hyperlight_common`

[danbugs]

hyperlight_common is using anyhow (

hyperlight/src/hyperlight_common/Cargo.toml

Line 19 in b9c67fb

anyhow = { version = "1.0.95", default-features = false }

) for its errors, which is probably not the most appropriate with it being a library. We should consider refactoring hyperlight_common to use thiserror like we do in hyperlight_host (

hyperlight/src/hyperlight_host/src/error.rs

Line 49 in b9c67fb

pub enum HyperlightError {

).
