WIP: Implement a component able to take a base 64 JSON encoded payload

[Akanoa]

Why this PR

I'd like to take the content of blocks and authorizer from a URL component.

I'd like also to be able to handle every playground parameter, because I'll pilot it from an iframe URL.

I'd like to add an export button to get the hash of the playground.

How

This component takes several attributes:

• fromHash : The base 64 JSON URL encoded of data
• displayFacts : Display or not the "Authorizer World"
• displayExternalKeys : Don't display the 3rd party private key
• showBlocks: Display other blocks than authorizer
• displayExport: Display the export button
• displayExternalKeys : Allow to use 3rd party blocks
• allowCustomExternalKeys : Allow to overwrite pre-defined 3rd party private key
• allowsRegenerate : Allow regenerate the biscuit private key

And show an export event, handling the hash of the playground content.

The data looks like:

{
    "code": "check if user(12);\nallow if true;",
    "blocks": [
        {
            "code": "user(12);",
            "externalKey": null
        }
    ]
}
