feat(new-tool): generate ula based on timestamp and mac address (#344)

Browse Source 
* feat(ipv6-ula-generator): new tool: generate ula based on timestamp and mac address

This new tool generates a random unique ula based on the current timestamp and the provided mac address. An ULA is your "secondary" IPV6-Address only for internal use.
It can also be used as a backup address if your provider gets offline and your Prefix-IPs are not longer valid.Also you can create the most of your internal firewall rules based on your ULAs.

* feat(ipv6-ula-generator): changes requested by review

* Update src/tools/ipv6-ula-generator/index.ts

* Update src/tools/ipv6-ula-generator/ipv6-ula-generator.vue
