ed448: Fix x448 private keys, to be 56 bytes, not 57
weierstrass: fix weierstrassPoints missing CURVE object by @secure12 in https://github.com/paulmillr/noble-curves/pull/92
utils:
- hexToBytes: speed-up 6x, improve error formatting by @arobsn in https://github.com/paulmillr/noble-curves/pull/83

First stable release. API should remain stable now.

ed25519, ed448: changed API

context is now an option in sign and verify
zip215 is a new verify option that allows to conform to RFC8032 when false. For true it will instead match ZIP215.
Added edwardsToMontgomery function

CURVE is no longer exposed, it was an internal property. Use G1.CURVE, G2.CURVE
Fields have been moved into fields: {Fp, Fp2, Fp6, Fp12, Fr} property
See README for new usage

weierstrass: improved DER decoding. Validate curve creation
Updated Wycheproof vectors to v0.9
