feat(maya): add other integration addresses

Issue being fixed or feature implemented

Support getting deposit addresses for other exchanges to use in Maya

How it is done:

ExchangeIntegrationProvider is injected into Maya to obtain a list of exchanges that is generated by the implementation in wallet.

Coinbase had all of the required API's. All that was added was a means to cache the accounts and their addresses.
Uphold support required a new API. A few other API's were implemented as suspend functions. These new methods will also save the accounts and addresses
ExchangeConfig is a class that will manage saving and retrieving accounts and addresses. Currently it saves a map of currency to account number as one map and account number to address in the second map. Perhaps it would be easier to simply have a single map to associate a currency with an address.
