v3.2.0

This release provides a workaround for the connection timeout issues being experienced by users connecting to the Ethereum node when using filters (which are the enablers for the Observables API). Details of the fix are available in #280, and the following issues, are useful for background #144, #279, #197.

It also provides ERC20 interfaces, which are a building block for the following issue which hopefully will be implemented in the near future. This is detailed in PR #239. Thanks to @eepstein for his contributions so far.
