Improve security by using audited cryptography libraries

[paulmillr]

You're using dependencies like:

airgap-coin-lib/packages/core/package.json

Lines 40 to 44 in 3c517e3

	"@stablelib/blake2b": "^1.0.1",
	"@stablelib/bytes": "^1.0.1",
	"@stablelib/ed25519": "^1.0.3",
	"@stablelib/nacl": "^1.0.4",
	"@stablelib/utf8": "^1.0.1",

These can be replaced by audited noble cryptography. It's fast and modern, supports ESM and tree-shaking.
