Metamask <> Avail snap adapter

Metamask <> Avail snap adapter is used to inject avail snap as web3 provider. It lists snap inside window.injectedWeb3["metamask-avail-snap"] so it can be enabled using @availproject/extension-dapp package.

For more details on avail snap itself see snap repo.

  config?: SnapConfig,
  snapOrigin?: string,
