Manually check correctness of `pros_sys` bindings.

[tropicaaal]

Problem Description

A lot of bindings from pros_sys are technically correct, in that they compile however there are some strange leftovers from bindgen inferring integer types that result in some inconsistencies which may be expensive to go back on once everything's stabilzed (such as enum reprs).

Additional information

At some point we should do a manual refactor of all the bindings in pros_sys to ensure they're following FFI best practices and are actually correct.
