52902e6fdf Implement Serde for fields and curves 
Currently Serde is only implemented for `Fp`, `Fq`, `EpAffine` and `EqAffine`.
Support can be enabled with the `serde` feature.

fb04f7ad99 Update to ec-gpu 0.2 release 
The traits of ec-gpu changed a bit, there's now also a `GpuName`
trait that needs to be implemented.

BREAKING CHANGE: `ec-gpu` v0.2 traits are not compatible with v0.1

All dependencies that use `ec-gpu` need to be on v0.2.

Merge pull request #30 from dot-asm/repr-c 
Add 'repr-c' feature to facilitate FFI.

870939ab03 Implement ec_gpu:GpuField for Fp/Fq 
This commit introduces a new feature called "gpu", which enables an
`ec_gpu:GpuField` implementation of `Fp` and `Fq`. This enables the
field arithmetics to be run on a GPU.

The code to convert from a u64 to a u32 vector was taken from
07a84f9727/src/lib.rs (L102-L108)

We also move this dependency behind the `alloc` feature flag, as it is
only required for `crate::hashtocurve`.

f874d29238 Remove FieldExt::rand 
This removes a dependency on the `getrandom` crate in no-std mode, which
doesn't work on some no-std targets that `getrandom` doesn't support.

ab03c3d5e1 Remove field traits from behind std feature flag 
Now that we have a default implementation of `SqrtRatio::sqrt_ratio`, we
can use it and `FieldExt` in no-std environments.

We introduce an `alloc` feature flag to form a common feature dependency
between `std` and `sqrt-table`. It is currently unused directly, but
will be used after `CurveAffine` is refactored to remove the `std`
dependency.

Closes zcash/pasta_curves#25.

314b1bcb94 Place SqrtTables behind a sqrt-tables feature flag 
This enables the crate to be compiled without the tables, instead using
a simple fallback for `SqrtRatio::sqrt_ratio`.

9999964d17 Add no-std support 
We re-introduce the Tonelli-Shank square root algoritm that was removed
in zcash/halo2#120, to use in no-std mode (the table-based impl requires
allocations, and also uses 29kiB of memory which is a problem for
constrained environments that typically need no-std).

b4ed5295fe Migrate to group traits 
The `Curve` trait is now `CurveExt: group::prime::PrimeCurve`, and
`CurveAffine` is now `CurveAffine: group::prime::PrimeCurveAffine`.

There is no `CurveAffine` trait in `group`, and it's a widely-used
trait in this crate, so we don't rename it to `CurveAffineExt`.
