Add combinatorial tests for internal Exchange functions (#807)
* WIP add combinatorial tests for internal Exchange functions * Change combinitorial testing strategy based on feedback * Check value of filled[orderHash] in updateFilledState tests * Add combinatorial tests for addFillResults * Add combinatorial tests for getPartialAmount * Implement generic `testWithReferenceFuncAsync` * Implement generic `testCombinatoriallyWithReferenceFuncAsync` * Add combinatorial tests for isRoundingError * Add combinatorial tests for calculateFillResults * Add support for Geth in internal contract tests * Fix contract artifacts * Change DECIMAL_PLACES to 78 and add a note. * Document new functions in utils * Optimize tests by only reseting state when needed * Rename/move some files * Print parameter names on failure in testWithReferenceFuncAsync * Add to changelog for utils package * Appease various linters * Rename some more things related to FillOrderCombinatorialUtils * Remove .only from test/exchange/internal.ts * Remove old test for isRoundingError and getPartialAmount * Appease linters again * Remove old todos * Fix typos, add comments, rename some things * Re-add some LibMath tests * Update contract internal tests to use new SafeMath revert reasons * Apply PR feedback from Amir * Apply PR feedback from Remco * Re-add networks to ZRXToken artifact * Remove duplicate Whitelist in compiler.json
