We're bumping from `^6` to `^8`. All imports are now named, and they have been updated. This is a breaking change, in that support for `eth_signTransaction` is added in `^8.0.0`. We do not support this method in our UI, so our middleware stack has been instrumented to reject.
In addition, there are some non-breaking behavioral changes in this version that reviewers should be aware of, see the [7.0.0 release](https://github.com/MetaMask/eth-json-rpc-middleware/releases).
Implement `eth_decrypt` and `eth_getEncryptionPublicKey`. This allows decryption backed by the user's private key. The message decryption uses a confirmation flow similar to the messaging signing flow, where the message to be decrypted is also able to be decrypted inline for the user to read directly before confirming.
* tests - create tests for pending middlewares
* transactions - add r,s,v values to the txMeta to match the JSON rpc response
* network - add new middleware for eth_getTransactionByHash that the checks pending tx's for a response value
* transactions/pending - use getTransactionReceipt for checking if tx is in a block
* meta - file rename
