Depends on D13358

Modify app to work with incremental parsing instead of repeated full parsing. Modified function parseWebsocketMessage to use new incremental functions instead of "do it all" functions. Handled special case of server startup and no aliases in the database, and added this case to aliasTestsLive.js

node index.js
Server starts up okay, adds unprocessed aliases to db
Stop the app
npm run live and tests pass
Delete your mongodb:

mongosh
use eCashAliases
db.confirmedTxHistory.drop()
db.validAliasTxs.drop()

Start the app again with node index.js. All aliases should process and add to db.
