Crate numcodecs_zfp

ZFP codec implementation for the numcodecs API.

This implementation uses ZFP’s ZFP_ROUNDING_MODE=ZFP_ROUND_FIRST and ZFP_WITH_TIGHT_ERROR=ON experimental features to reduce the bias and correlation in ZFP’s errors (see https://zfp.readthedocs.io/en/release1.0.1/faq.html#zfp-rounding).

This implementation also rejects non-reversibly compressing non-finite (infinite or NaN) values, since ZFP’s behaviour for them is undefined (see https://zfp.readthedocs.io/en/release1.0.1/faq.html#q-valid).

Please see the numcodecs-zfp-classic codec for an implementation that uses ZFP without these modifications.
