useUnifiedTopology=true needs to be in db_url (updated package.json attached, also)

[TinosNitso]

I set db_url (in index.js) to
mongodb://tinos.ml:27017/?useNewUrlParser=true&useUnifiedTopology=true&connectTimeoutMS=3600000&socketTimeoutMS=1200000
Worst case scenario for slpdb we can set a 20min (or 1hr) timeout & if anything ever goes wrong it takes at least 20 mins for the crash to occur & a .sh or .bat script to $0 or %0 restart the whole process. The timeout sets the time for the server to effectively reboot if something bad happens.
I've raised a Windows compatibility issue with fountainhead-core. It turns out it can use mongodb module v4, whereas SLPDB only supports v3.
Here is the package.json I used to npm install in Win10. However I'll be switching back to WSL1 (Ubuntu) today, since there is a bug in node.exe which makes both SLPDB & SLPServe extremely slow. I decided to waste a couple days proving it to myself. Node doesn't really support Windows! More updates to the dependencies below are possible, these are just what I used to try speed up the Windows version:

  "dependencies": {
    "bignumber.js": "~9.0.0",
    "bitcore-lib-cash": "8.25.36",
    "cors": "^2.8.5",
    "dotenv": "16.0.1",
    "ejs": "^2.6.1",
    "express": "^4.16.3",
    "express-rate-limit": "^3.3.2",
    "fountainhead-core": "0.0.12",
    "iconv-lite": "0.6.3",
    "ip": "^1.1.8",
    "mongodb": "4.9.0",
    "node-jq": "2.3.3",
    "p-queue": "3.2.0",
    "traverse": "0.6.6",
    "zeromq": "^5.2.8"
  }

I also set slpserve_timeout : 300000 due to extreme slowness in Windows. (I happen to know WSL1 is faster than WSL2 which is faster than Hyper-V which is faster than VirtualBox, and I was truly astounded that node.exe may be even slower than VBox.) Btw my exact version is v16.17.0 (v17 & up no longer support RIPEMD160).
I'm running SLPDB instance currently at slpdb.tinos.ml.
I also have a running sync journal on Reddit, here.
