PyCon US 2024

Resolves #1165

[jonafato]

This is a draft of the PyCon US 2024 videos data set. It should be largely complete, but I need to manually clean up a few issues before it can be merged:

• Some talks may be missing videos. These should be corrected if the videos are available or removed if they are unavailable / private.
• Only one session of lightning talks is present, so the others should be added.
• Speaker info may be missing when the official PyCon US API response did not include it (e.g. in the "Welcome" session). These cases should be fixed.

Edit: these issues are fixed, and the data is mostly complete regarding what's published to YouTube so far. If any additional videos get published to YouTube later, the information can be filled in. One additional task is to fill in all of the speakers for the lightning talk sessions.
