NIST P256 signatures for Cortex-M4 microcontrollers

## What is this? Sometimes NIST P256 signatures need to be used. This is an attempt to create a library that is misuse-resistant for that. The intended targets are Cortex-M4 and Cortex-M33 microcontrollers. As backend, we use [micro-ecc][micro-ecc], exposed via [micro-ecc-sys][micro-ecc-sys].
