Exporting new utility functions for amounts. This includes new functions:

getUnlimitedOrderAmounts getBuyAmountFromPrice getUnitPrice

and should make integration projects easier!

This release includes a new streamed event-based orderbook. Additionally the codebase has been partially migrated to TS, so there should be improved support for using this package with TypeScript.

Breaking Changes:

export interface OrderBN { ... }
export decodeOrdersBN(...)
export const BatchExchange = ...
export const BatchExchangeViewer = ...

Is now:

export interface Order<BN> { ... }
export decodeOrders(...)
export const BatchExchangeArtifact = ...
export const BatchExchangeViewerArtifact = ...
