Add file and page tags to the cache file

[adisney]

I'm working on a personal project that will require inspecting files that have specific tags on them. As a part of doing that, I have modified rmapi to include the names of the tags that have been applied to the top level file or to specific pages within a file.

This may address some what is desired in issue #249.

The file tags are in the fileTags field.

"fileTags": [
    {
        "name": "Daily",
        "timestamp": 1655955509272
    }
]

The page tags are in the pageTags field.

"pageTags": [
    {
        "name": "Planning",
        "pageId": "016892c0-1a4c-44e2-93d3-23b1f111a858",
        "timestamp": 1670176484275
    }
]

The updated cache file entry for a file with tags will look like the following:

{
    "coverPageNumber": 0,
    "documentMetadata": {
    },
    "dummyDocument": false,
    "extraMetadata": {

@adisney this looks great to me

[juruen]

should we return the error here?

[adisney]

Yes, I should have done that initially. Updated.

@adisney I know this is an old pull request, but how do I access the tags from the interface or from the ctx *ShellCtxt?

It doesn't show up in stat and from what I can tell as someone with little go experience it's not part of the node either.

Note, I ported this PR to the current main branch as it didn't work as-is, probably because of updates to the API. The variables are present on the blob document but I have no idea how to access them.
