Older versions depend on the deprecated ethereum-* libraries instead
of the newer eth-*, which cause a deprecation notice.

Manticore 0.3.6 causes issues when running etheno, see issue
#80 for the details.

The upstream bug in ganache-cli appears to have been fixed.

…uest object modular

Two changes:
1. Removed unused code that was dependent on using integers as the mapping for EventPlugin._transactions mapping and for converting hashes into hex strings
2. Moved get_transaction_receipt_request into etheno.py so that both clients and plugins can use itt.

Used `black` to make code PEP 8 compliant

Fix issue with function call logging and PEP 8 Compliance

There have been a lot of changes that need to be pulled in to make development on this branch much easier.

It is easier to parse and compile individual contracts than to read the entire file and then separate into separate byte arrays for compilation.

1. Added command line argument to enable compilation of ArbSys and ArbRetryableTx
2. Created Precompiler EthenoPlugin that successfully compiles ArbSys.sol
3. Added logic to __main__.py to add Precompiler as an EthenoPlugin if the command-line argument is set to True and Ganache is the RPC Provider

`solc` was complaining that all functions that were inherited from the ArbRetryableTx interface need to have the `override` modifier. Thus, the modifiers were added

Here are the key changes:
1. Made finding the final offset in `precompiler.compile()` more flexible (note that only the last contract in a .sol file is deployed)
2. `etheno.deploy_contract` now returns a hex string instead of an int. The rationale for this is explained in the commend above that return statement.
3. Both ArbSys and ArbRetryableTx are now being deployed via Ganache.
4. Improved error handling for not finding files or unsuccessful compilation
