[REVM 3.2.0] revm-primitives does not compile

[ufoscout]

I upgraded a project from version 3.0.0 to 3.2.0, now the project compilation fails with this error:

error[E0599]: no method named `to_string` found for enum `FromHexError` in the current scope

help: the following trait is implemented but not in scope; perhaps add a `use` for it:

What features do you have enabled?

[ufoscout]

only serde. If I remove that feature, it compiles

[rakita]

for quick fix, include std, and will make the proper PR to fix it.
