Script intented to check a domain expiration with a query to the corresponding
RDAP server.
RDAP server. The RDAP server for the TLD is extracted from the IANA JSON RDAP.
If the expiration field isnt found on the TLD server, the script falls back to
the registrar server.
This script is inspired from
https://raw.githubusercontent.com/buanzo/check_expiration_rdap/main/src/nagios_check_domain_expiration_rdap/nagios_check_domain_expiration_rdap.py

The script assumes that the TLD has only one label while looking for the RDAP
server from the IANA JSON. If its not the case it will fail.
I dont understand half of what I wrote
Have fun.
For all the options, run `./check_domain_expiration_rdap.py -h`
Here are the tested cases:
```shell
# expired domain
