Initial Bifrost 2 Structure

This PR contains the base set up for Bifrost 2 (the new Python SDK for DCP). It outlines the file structure of the module, and the dev tools used (poetry for Python management and testing, pminit for npm install for instance).

Module logic is in dcp/, tests are in tests/...

dcp.api

• bifrost 2 specific hard coded api features
• for instance: this is where job.wait() and compute_for live

dcp.dry

• generics used for programmaticly generated structures
• for instance, the class maker functionality lives here for auto generating Bifrost2 versions of js/pm classes

dcp.js

• JavaScript code specific to Bifrost2 lives here
• for instance, the node modules required by Bifrost 2 such as dcp-client

(note: the file structure is subject to change and may have changed by the time you review this PR)

Module initialization algorithm

When dcp.init() is called a module system is programatically generated which matches the JavaScript CJS modules. At the same time, any classes, or functions come across are automatically converted to more Pythonic structures.

List of things this PR does

• Transforms the CJS JS module we get from PythonMonkey requiring dcp-client into a Python module
• Wrap raw PythonMonkey JSProxy so they abide by the Bifrost 2 Spec
• Pythonic asynchronous behaviour
• Initial setup for additional api to be hooked in easily
• Tests

[wiwichips]

internal implementation details are leaked when one imports dcp, need to limit that

[wiwichips]

bfclass class maker is ugly and should be cleaned up
