Add WP-CLI command to bulk process excerpts

[dkotter]

Description of the Change

In #405 we added the ability to manually generate excerpts on individual items. This is a follow up that adds a WP-CLI command that can be used to process items in bulk, adding generated excerpts to those items.

One thing to note is that OpenAI has rate limits on their APIs, so you may run into that if processing too many items at a time. For instance, free accounts only get 3 requests per minute on the ChatGPT API, so very easy to hit that. Paid accounts go up to 3500 requests per minute, so unlikely to run into issues. We may want to explore adding rate limiting into ClassifAI at some point to ensure these limits aren't hit.

The new command looks like:

wp classifai generate_excerpt

and has the following options:

• A comma-delimited list of post IDs to process
• A post_type argument that will be used if no post IDs are passed in
• A post_status argument that will be used along with the post_type argument. Defaults to publish
• A per_page argument. This controls how many items we process in each batch. Defaults to 100. As an example, if you have 1000 items to process, all of these will be processed but will be done in batches of 100 for performance reasons
• A force argument that defaults to false. Will only process items that don't have an excerpt set if set to false
• A dry-run argument that defaults to true. You must pass false to actually run the command

Here are some example commands that can be run:

wp classifai generate_excerpt 1,2,3 --dry-run=false

wp classifai generate_excerpt --post_type=post --dry-run=false

wp classifai generate_excerpt --post_type=page --per_page=5 --force=true --dry-run=false

Closes #416

How to test the Change

Try running some of the WP-CLI commands as described above and ensure they all work as expected

Thanks for adding this @dkotter. This looks great and works well. I haven't tested with large dataset but looks great. 🚀

Added some nice to have notes, but not necessary to fix to merge this

Thanks.
