a8583dd818 Auto merge of #71 - ebfull:expose-arith, r=ebfull
Expose arithmetic

This exposes `adc`/`sbb`/`mac_with_carry` from this library for downstream use, as long as a `expose-arith` feature is enabled. We need this downstream to avoid code duplication.

This also bumps to `0.13.2`.

The `mod q` stuff was spotted by @Pratyush and/or @howardwu.

I just noticed the `// 2` typo.

ed5a7f31e2 Auto merge of #69 - ebfull:0.13.1-release, r=ebfull
Release of 0.13.1

This release features the following changes:

* The `byteorder` version is now set to `1` as conventional.
* The `CurveAffine`/`CurveProjective` traits now enforce that the scalar field of the `Engine` is the same scalar field for the curves.
* `Engine` is now `'static` and `Clone` to avoid problems with lifetime quirks and auto-derives.
* The scalar field of `Engine` is now guaranteed to be `SqrtField` which helps downstream abstractions.

In this PR I will be updating the `clippy` version and fixing any linting problems that show up. The builder should be using the newest nightly/stable versions of Rust also.
