Support for alt_text in media uploads

[basinbasin]

I'd like to add alt_text to media uploads when using TweetMoaSharp but it's not clear if
media/metadata/create from the Twitter API is supported?

API: https://developer.twitter.com/en/docs/twitter-api/v1/media/upload-media/api-reference/post-media-metadata-create

Thanks

It's been a while but my reading of the source code is that

Init
Append
Finalize
CheckStatus

for media are all supported. However I do not think any of the metadata or subtitle endpoints currently are, sorry, so it doesn't look like alt text is currently supported :(
