Replace contract client references with Arc (#35)
* feat(provider): allow specifying a default polling interval param

This parameter is going to be used for all subsequent client calls by default. It can still be overriden with the internal
`interval` calls

* feat(contract): replace reference to Client with Arc

* feat(abigen): adjusts codegen to use Arcs

* fix(ethers): adjust examples to new apis

* fix(provider): return TxHash instead of PendingTransaction on tx submission

Returning a PendingTransaction allowed us to have nice ethers.js-like syntax where you submit
a transaction and then can immediately await it. Unfortunately, now that we use Arcs and not lifetimes
this meant that we would need to bind the function call in a variable, and then await on it, which is pretty
bad UX.

To fix this, we revert back to returning a TxHash and introduce a convenience method on the provider and the
contract which takes a tx_hash and returns a PendingTransaction object. The syntax ends up being slightly
more verbose (although more explicit), but the issue is fixed.

Add streamed logs to the provider (#9)
* 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
