Feature Request: adding metadata label 1870 for verifiable achievements and credentials

[PierreManos]

So far the metadata editor on pool.pm is limited to CIP 25 and the 721 label, so only this label is viewable on the website even if a transaction has other labels attached to it.

We propose to add label 1870 to pool.pm's metadata editor as it has a widespread adoption potential as discussed on this merged commit of CIP 10.

What is label 1870?
The label 1870 is the Open Badges v2.0 compliant metadata

Open Badges is an open standard originally developed by the Mozilla Foundation and now maintained by IMS Global to represent verifiable achievements (e.g. educational certificates or certificates from instructional lectures).

Open Badges are information-rich visual tokens of verifiable achievements earned by recipients and easily shared on the web and via social media. The Open Badges standard describes a method for packaging information about accomplishments, embedding it into portable image files as digital badges, and includes resources for web-based validation and verification. Open Badges describe who earned it, who issued it, the criteria required, and in many cases even the evidence and demonstrations of the relevant skills.

The standard has a widespread adoption. An example of a use case is the issuance of achievement badges for the UZH Summer School 2022.
