In all the other chains we take the provider directly, I would suggest to do the same (as providers might need API Keys)

I feel that this library in particular should not handle the isAccountDoesNotExistError, since by nature chainsig.js only handles getting signatures
Otherwise, the chains acts in one way for NEAR, and in a totally different for the other chains
Here we could either return 0 on error (which would make sense) or raise the error further app

this look weird to me, since I would have expected the derived account to be:
- either an
implicit account - either
${predecessor}(always returnpredecessorindifferent to thepath)
