FEATURE: Use actual Canto tags

[danielkestler]

Info, this is based on the PHP8-compatible PR from @markusguenther.

This PR adds the feature to use actual Canto tags instead of custom fields to use in the media browser. I don't know if you need/want this, or if there were any reasons to omit this feature and use custom fields in the first place.

It is configurable, similar to the custom fields mapping:

Flownative:
  Canto:
    # At the moment, this is "either or", so use custom fields or tags for mapping, not both
    mapping:
      # map "Custom Fields" from Canto to Neos
      customFields: []
      # map "Tags" from Canto to Neos
      tags:
        field: 'tags'
        limit: 20
        include: []
        exclude: ['Untagged']

Asset count per tag is cached for performance reasons for one hour.

A new CLI command "importtags" can be used to import the tags first, then they are shown in the media browser.

Thanks, I'll have a look!

Yes, the first sponsor of this package didn't use tags, but custom fields… 😎

BTW, this was planned to be done eventually, see #17

Thank you. By the way, my implementation should cover different use cases, by setting the "field" property in the configuration above, one could also use the Canto "keywords" for example.

(TBH, I also thought about a general solution where one could configure the custom fields here, so one place to configure where tags (and maybe asset collections) are fed from.)

BTW: I updated the PHP 8 PR because there were some issues left.
So maybe this needs a rebase ;)

[danielkestler]

Thank you, merged the changes.

@danielkestler The "base PR" is now merged and a few changes followed. Maybe you could rebase this PR, so we can get a fresh look? Thanks!

[danielkestler]

Thank you. As I am always having problems rebasing, and I saw there is a lot of things now in the main branch including caching, I have rewritten it on the current main branch and made a new PR here: #31
