Feature request - Use Google DNS API for looking up DNS records

Using Google DNS API for looking up DNS records might help speed up the code, plus it will truly be multi platform.

Example

## Domain
$Domain = '<some_domain>'

## Uri
### All
$Uri = 'https://dns.google.com/resolve?name={0}&type=all' -f $Domain
### A
$Uri = 'https://dns.google.com/resolve?name={0}&type=a' -f $Domain
### MX
$Uri = 'https://dns.google.com/resolve?name={0}&type=mx' -f $Domain
### TXT
$Uri = 'https://dns.google.com/resolve?name={0}&type=txt' -f $Domain

## Request
(Invoke-RestMethod -Uri $URI -Method 'Get').'Answer'

## AIO SPF
([array]((Invoke-RestMethod -Uri ('https://dns.google.com/resolve?name={0}&type=txt' -f $Domain) -Method 'Get').'Answer'.Where{$_.'data' -like '"v=spf1*'})).'Count' -gt 0
