Implement custom activity text for TV show episodes

[hozarho]

Solves #174

Tested very briefly, but looks like it works as intended.

Example

// [...]
"shows": {
  "display": {
    "details_text": "S{season-padded}E{episode-padded} - {title} {sep} {original-title}",
    "state_text": "{genres} {sep} {studio}",
    "image_text": "{show-title} ({year})"
  },
  "separator": "•"
},
// [...]

Result

Changes

• Add support for display custom activity text formatting for TV show episodes
• API changes:
  • removed episode_display_options from Client struct in lib.rs - no longer used, replaced by shows_display_options
  • it's now possible to convert EpisodeDisplayOptions struct to DisplayFormat
• Works with legacy configuration (show_simple, append_prefix and add_divider) if shows.display is not specified in the config.
• Supported formatting items:
  • {show-title} - the TV show title
  • {title} - title of the episode
  • {original-title} - title of the episode in its original language
  • {episode} - number of the episode, not padded - for example 5
  • {episode-padded} - number of the episode, padded with zero - for example 05
  • {season} - number of the season, not padded - for example 2
  • {season-padded} - number of the season, padded with zero - for example 02
  • {year} - release year of current episode
  • {genres} - TV show genres
  • {studio} - studio of the TV show
  • {version} - Jellyfin-RPC version, used for default image_text
  • {sep} - separator
• Added formatting item for movie display:

  • {original-title} - movie title in its original language

    // [...]
    "movies": {
      "display": {
        "details_text": "{title} ({year}) {sep} {original-title}",
    // [...]

Looks like CI is broken, but i'll try it out once it works again.

I went ahead and just built it locally just to try it out.

Is it possible to also add SeriesStudio as {studio} and OriginalTitle (which is already there in the class) as {original-title}?

Probably also add original_title to the other 2 media types as well.

I also went ahead and edited the wiki. Apologies if I jumped ahead - https://github.com/Radiicall/jellyfin-rpc/wiki/Jellyfin

I was able to add {original-title} and {studio}.

Example

// [...]
"shows": {
  "display": {
    "details_text": "S{season-padded}E{episode-padded} - {title} {sep} {original-title}",
    "state_text": "{genres} {sep} {studio}",
    "image_text": "{show-title} ({year})"
  },
  "separator": "•"
},
// [...]

Side Note

I tried to also add fields for production year of the show itself and original series title, but for now I don't know how to approach it any different way than applying a workaround to get userId by username from /Sessions and then getting item info via /Users/{userId}/Items/{itemId}, as apparently directly requesting GET /Items/{itemId} is not possible using authentication via API key. I think changing approach regarding authentication and adding workarounds is beyond the scope of this issue. Therefore, series-related fields are missing for now.
