New release: dnscontrol v3.22.0

[Tom Limoncelli]

https://github.com/StackExchange/dnscontrol/releases/tag/v3.22.0

This release adds new functionality to the `IGNORE_NAME()` function,
supports DNSimple's API change, and improves documentation.

`IGNORE_NAME()` is now more flexible about what it can ignore. You
can now restrict its ignorance (ignorefullness?) to specific DNS
resource types. For example, instead of ignoring all DNS records at
`foo.example.com`, you can ignore just the `A` records, or just the
`A` and `TXT` records. Thanks to @bits01 for this contribution!
