INWX: Support up to 2,147,483,647 domains (old limit was 20)

I'd propose this simple "fix" (I guess rather workaround?) to use more than 20 domains on INWX. I have verified it working.

Without this line:

******************** Domain: dnscontrol20.com
3 corrections (INWX)
#1: + CREATE A dnscontrol20.com 1.1.1.1 ttl=300
#2: ± MODIFY NS dnscontrol20.com: (ns.ote.inwx.de. ttl=86400) -> (ns.ote.inwx.de. ttl=300)
#3: ± MODIFY NS dnscontrol20.com: (ns2.ote.inwx.de. ttl=86400) -> (ns2.ote.inwx.de. ttl=300)
******************** Domain: dnscontrol30.com
WARNING: Zone 'dnscontrol30.com' does not exist in the 'INWX' profile and will be added automatically.
WARNING: No nameservers declared; skipping registrar. Add {no_ns:'true'} to force.
Done. 3 corrections.

When applying:

Done. 6 corrections.

All values larger than 2147483647 will exceed int type defined in goinwx go library and will fail. I'd think the chance of having more than two billion domains is very unlikely and is the simplest fix avoiding to implement entire paging system.

This fixes #2512

I love this kind of fix. I don't understand why providers think small page sizes are fine.
