feat: import everything from tweetnacl?

[peterpeterparker]

Is your feature request related to a problem? Please describe.
While having a look at the size of agent-js I noticed tweetnacl which is currently imported with a wild card

import * as tweetnacl from 'tweetnacl';

Is there a chance that importing only the resources needed would spare few kb of code that is not needed here?

Additional context

[peterpeterparker]

Btw. do agent-js still needs that lib or can use the platform API instead?

[peterpeterparker]

Same for import * as cbor from 'simple-cbor'; btw.

I can investigate the size impacts!

Unfortunately, web SubtleCrypto doesn't support ED25519, so we're dependent on a library for the time being

[paulmillr]

you folks should use noble-curves or noble-ed25519 instead, tweetnacl is not secure

[krpeacock]

Tweetnacl is removed in #784 in favor of noble-curves
