dehydrated: Update to version 0.7.1

- Update from version 0.7.0 to 0.7.1
- Update of rootfile not required
- Changelog
    ## [0.7.1] - 2022-10-31
	## Changed
		- `--force` no longer forces domain name revalidation by default, a new argument `--force-validation` has been added for that
		- Added support for EC secp521r1 algorithm (works with e.g. zerossl)
		- `EC PARAMETERS` are no longer written to privkey.pem (didn't seem necessary and was causing issues with various software)
	## Fixed
		- Requests resulting in `badNonce` errors are now automatically retried (fixes operation with LE staging servers)
		- Deprecated `egrep` usage has been removed
	## Added
		- Implemented EC for account keys
		- Domain list now also read from domains.txt.d subdirectory (behaviour might change, see docs)
		- Implemented RFC 8738 (validating/signing certificates for IP addresses instead of domain names) support (this will not work with most public CAs, if any!)
