Binance no support for BCC because of ccxt BCH rename

[Haehnchen]

In https://github.com/ccxt/ccxt/blob/master/js/binance.js#L737 binance BCC are named to the common name BCH. products.json does not support it. Products generator should respect this rule.

zenbot backfill binance.BCH-USDT --days=5

eg add this to products.json

{
    "id": "BCHUSDT",
    "asset": "BCH",
    "currency": "USDT",
    "min_size": "0.00001000",
    "max_size": "100000",
    "increment": "0.01",
    "label": "BCH/USDT"
},

Hi, please place this in /extensions/exchanges/binance/update-products.sh:

#!/usr/bin/env node
let ccxt = require('ccxt')
let n = require('numbro')
new ccxt.binance({ 'apiKey': '', 'secret': '' }).fetch_markets().then(function(markets) {
  var products = []
  markets.forEach(function (market) {
    products.push({
      id: market.id,
      asset: market.base,
      currency: market.quote,
      min_size: market.info.filters[1].minQty,
      max_size: market.info.filters[0].maxPrice,
      increment: market.info.filters[1].stepSize,
      label: market.base + '/' + market.quote
    })
  })
  var target = require('path').resolve(__dirname, 'products.json')
  require('fs').writeFileSync(target, JSON.stringify(products, null, 2))
  console.log('wrote', target)
  process.exit()
})

I'm currently unable to do a pull request, so if anyone has time to add this script in it, that would be great.
