This commit moves all #[derive] annotations behind Cargo feature gates to add
the ability to strip them all out entirely. The `Clone` and `Copy` impls
continue to be enabled by default as they tend to be mega useful but other
equality/hash/debug impls are all default behind the `extra-impls` gate.
This commit, on my computer, has the following timings:
| features | before | after
|-------------------------------|---------|------
| default | 3.67 | 2.96
| *none* | 1.78 | 0.49
| {printing, parsing} | 3.71 | 2.57
| default + {full} | 8.50 | 6.31
| {full} | 3.53 | 0.70
| {full, printing, parsing} | 8.10 | 5.29
Closes #143
