Support RPC filters in web3.js

[tomjohn1028]

Problem

I'm looking to subscribe to a program via the web3.js Connection.onProgramAccountChange, but I'd like to use the optional filter that comes with the underlying RPC programSubscribe request.

Proposed Solution

Update the build arguments of a subscription to include optional filters argument. As of writing the _buildArgs method seems to only take in a programId and commitment. It seems like it could be easily passed in to the extra argument of the buildArgs.

1. Update onProgramAccountChange to include optional filters in the subscription object
2. update program subscription builder (here) to pass in the filters as the extra arg
