Upstream release: [v1.0][upstream-release]

[nisty]: https://crates.io/crates/nisty
[upstream-release]: https://github.com/kmackay/micro-ecc/releases/tag/v1.0
## Building / Usage
`bindgen` as build dependency triggers the cargo build bug,
`no_std` platforms need pre-generated bindings.
For Cortex-M4 and Cortex-M33 platforms, these are [packaged][cortex-m4-bindings].
To verify locally, run `cargo build --target thumbv7em-none-eabi --no-default-features`
and compare with the packaged file.
To use on such platforms, include `micro-ecc-sys` without the default features:
```
[dependencies.micro-ecc-sys]
default-features = false
```
