onTrades for funding trades does not call the handler

[dutu]

Issue type

• bug
• missing functionality
• performance
• feature request

Brief description

The handlers registered for public funding trades with onTrades are not called when fte/ftu messages are received.

This is because the fte/ftu messages are not properly handled and the messages don't propagate to listener registered with onTrades method.

Steps to reproduce

const ws = new WSv2()

ws.on('open', async () => {
  ws.onTrades({ symbol: 'fUSD' }, (trades) => {
    console.log('recv trades: %j', trades)
 })

  ws.subscribeTrades('fUSD')
})

await ws.open()

Additional Notes:

Possible bug fix:

Change

bitfinex-api-node/lib/transports/ws2.js

Lines 967 to 971 in fabfc1c

	const eventName = msg[1][0] === 'f'
	? msg[1] // Funding trades are passed to fte/ftu handlers
	: msg[1] === 'te'
	? 'trade-entry'
	: 'trades'

with

    const eventName = msg[1] === 'te' || msg[1] === 'fte'
        ? 'trade-entry'
        : 'trades'
