* (feat) gas oracle support
* (refactor) make a separate module | fix clippy warning
* add gas oracle to client using dynamic dispatch
* fix doc build in multicall module
* gas oracle returns U256
* support gas price fetching from client
* avoid querying for unsupported gas categories
* changes based on PR review
* add support for gasnow API, refactor gwei to wei
* fix: relax trait bounds on JsonRpcClient
* refactor(provider): move http client to separate dir
* feat(provider): add initial Websocket support over Stream/Sink + Tungstenite
* test(provider): add websocket test
* feat(provider): add convenience method using tokio/async-std behind a feature flag
* test(provider): add websocket ssl test
* feat(provider): add TLS websockets for tokio/async-std
* docs(provider): add websocket docs / examples
* fix(provider): make tokio an optional dep
* feat(types): add optional Celo support
* feat: add Celo feature flags to all crates
* test(provider): add get_transaction celo test
* test(signer): add send_transaction celo test
* test(contract): add deploy and call contract function celo test
* fix(provider): ensure the Pending transaction calls the waker to get polled again
* feat(core): allow setting the blocktime in ganache
* test(provider): move pending txs test to integration tests + use block time
* fix(signers): make EIP-155 optional and fix sighash generation bug
* feat(provider): implement Streamed logs
This utilizes eth_getFilterChanges. The stream struct must be instantiated with a factory that yields logs/hashes.
Consumers are expected to use the `FilterStream` trait in order to simplify their type definitions
* feat(provider): expose streaming methods
* test(provider): add new blocks/pending txs test
* feat(contract): allow events to be streamed
* test(contract): add integration test for streaming event logs
* perf(contract-factory): take abi and bytecode by value instead of reference
The abi, bytecode and the factory's deploy method now consume the structs instead of being passed by reference. While this means that
consumers might need to clone before using them, this gives us some more flexiblity around factories inside helper functions
* refactor(contract): use test helpers to reduce code dup
* chore: make clippy happy
