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`.

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.
