doesn't cache the output of the proc macro, and using the derive form of this code can cause slowdowns in `cargo check` and `rust-analyzer`. As an alternative, this commit introduces an option to generate the `PrimeField` implementation in a `build.rs` script, to avoid the slowdown.

This PR is now almost entirely the codegen changes, which cannot be reviewed in the same PR as the trait changes. So I'm going to make my own PR on top of #93 that adds the associated constants, and we can use that to investigate the ecosystem and confirm whether it will cause any issues for downstream trait implementors (#87 (comment)). |

This MR exposes the
zero,one, andmultiplicative_generatorvalues as constants rather than functions. It might be preferred to only have the constants version---and I'm happy to make that change if so---but for now I've left the original function versions as well.
