making posts with mentions and URL cards

[MostWrong]

WIP: idea is to use resolveHandle to populate the facets field in the post request JSON along with start and end position for the mention (anything starting with an @ and has spaces in the beginning/end and resolves to a handle)

for URL cards, thinking of something like this - https://github.com/aliceisjustplaying/atproto-starter-kit/blob/main/index.ts

cool!

this is how i'd go further:

• open "new post" dialog
• open dev tools (ctrl shift i)
• open network pane
• click the clear button
• type hello @typeofemale.ingroup.social
• click Post
• look for the resolveHandle and createRecord
• look at the createRecord payload and response
• copy these into the python code ^^

mentions are done ( and tested ) , now I guess it's time to add support for URL cards ( same PR)

[MostWrong]

@ianklatzco slightly confused about adding support for URL cards; as the user can ideally place the link anywhere within the text should I just make a method which takes in a substring of the skoot; or a starting and ending position?

[ianklatzco]

at a first glance without thoroughly understanding, start/end positions is probably the right way to do it because that's how the twitter API works for knowing where to highlight urls. looking closer....

Trying to understand what facets are:

• looks like fields in a record that contain things like "urls in this skoot?"

if you're feeling it, maybe split get_invites and facets into two separate PRs? that way i can quickly merge the get_invites one, and we can cleanup the facets one to merge cleanly after ^^
