Document cargo features

Credit to @hinto-janai for adding such sections to their work on documenting
monero-serai in #568.

@@ -17,3 +17,12 @@ monero-serai was written for Serai, a decentralized exchange aiming to support
 Monero. Despite this, monero-serai is intended to be a widely usable library,
 accurate to Monero. monero-serai guarantees the functionality needed for Serai,
 yet does not include any functionality specific to Serai.

+- `std` (on by default): Enables `std` (and with it, more efficient internal

+- `compile-time-generators` (on by default): Derives the generators at
