48d3fbef5c std/fmt/index.zig: set width from 0 to 2; 
\x00 was printed as 0 and \x0E was printed as E;
\x00 now correctly prints 00 and \x0E correctly prints 0E;

38399941d4 std/crypto: Update throughput_test.zig to include all hash functions 
This avoids the need to recompile to test specific hash functions. This
also adds mac/key exchange performance tests as well.

This also adjusts the current hash/hmac functions to have a consistent
interface allowing easier switching/testing.

65b89f598c Add poly1305 and x25519 crypto primitives 
These are translated from [monocypher](https://monocypher.org/) which
has fairly competitive performance while remaining quite simple.

Initial performance comparision:

Zig:
 Poly1305: 1423 MiB/s
 X25519:   8671 exchanges per second

Monocypher:
 Poly1305: 1567 MiB/s
 X25519:   10539 exchanges per second

There is room for improvement and no real effort has been made at all in
optimization beyond a direct translation.

87eb95f816 speed up chacha20 
The main changes are:

    Unrolling the inner rounds of salsa20_wordtobyte which doubles the speed.
    Passing the slice explicitly instead of returning the array saves a copy (can optimize out in future with copy elision) and gives ~10% improvement.
    Inlining the outer loop gives ~15-20% improvement but it costs an extra 4Kb of code space. I think the tradeoff is worthwhile here.
    The other inline loops are small and can be done by the compiler if it is worthwhile.
    The rotate function replacement doesn't alter the performance from the former.

The modified throughput test I've used to benchmark is as follows. Interestingly we need to allocate memory instead of using a fixed buffer else Zig optimizes the whole thing out.

Fixed compile error when passing enum to fmt 
Caused by struct printing behavior. Enums are different enough from structs and unions that the field iteration behavior doesn't do what we want even if @memberName didn't error on enums.
