Request for a less restrictive Provider type in retrieveAndDecrypt.

[jdbertron]

Can we make the type less restrictive for the provider in retrieveAndDecrypt() ?
public async retrieveAndDecrypt( provider: ethers.providers.Web3Provider, conditionExpr: ConditionExpression, variant: FerveoVariant, ciphertext: Ciphertext ): Promise<Uint8Array> {

Not everyone will use a Web interface and Wallet to connect. I'm using it within a node.js application and a JsonRpcProvider.
Using ethers it's probably OK to just use the generic Provider interface.

Hi @jdbertron, we've switched to a more permissive provider type, ethers.providers.Provider, in this PR: https://github.com/nucypher/nucypher-ts/pull/270/files#diff-aea7a7ec89768972146f36cc3bc087e392dffdccbe6cde4790183ae3ed77de92R48-R49

These changes will be available in the next alpha release.
