Mautrix-instagram

* **Security:** Updated Pillow to 10.0.1.
* Added support for double puppeting with arbitrary `as_token`s.
See [docs](https://docs.mau.fi/bridges/general/double-puppeting.html#appservice-method-new) for more info.
* Updated attachment upload API as the old one was slow.
* Changed error for expired media to look more like what Instagram shows and
less like the bridge is broken.

* Improved handling of some message types.
* Added automatic retrying for sending videos to give Instagram servers more
time to transcode the video.
* Added support for -mentioning users from Matrix.
* Added support for bridging incoming avatar stickers.
* Added automatic fetching of shared reel videos to bridge full video instead
of only the thumbnail image.
* Added real-time bridging of group avatar changes from Instagram.
* Added option to disable sending typing notifications to Instagram.
* Added notice message when receiving video calls.
* Added options to automatically ratchet/delete megolm sessions to minimize
access to old messages.
* Added option to not set room name/avatar even in encrypted rooms.
* Redid backfill system to support MSC2716.
* Note that using Synapse's MSC2716 implementation is not recommended, and
the bridge can still backfill messages without MSC2716.
* Implemented appservice pinging using MSC2659.
* Possibly improved MQTT connection handling.

* Added support for "mentioned in comment" messages.
* Added support for re-requesting 2FA SMS when logging in.
* Updated Docker image to Alpine 3.17.
* Fixed error in image bridging.
* Fixed logging in with phone/email in provisioning API.

* Added option to send captions in the same message using [MSC2530].
* Updated app version identifiers to bridge some new message types.
* Fixed race condition when backfilling chat with incoming message.

[MSC2530]: https://github.com/matrix-org/matrix-spec-proposals/pull/2530

* Fixed login breaking due to an Instagram API change.
* Added support for SQLite as the bridge database.
* Added option to use [MSC2409] and [MSC3202] for end-to-bridge encryption.
However, this may not work with the Synapse implementation as it hasn't been
tested yet.
* The docker image now has an option to bypass the startup script by setting
the `MAUTRIX_DIRECT_STARTUP` environment variable. Additionally, it will
refuse to run as a non-root user if that variable is not set (and print an
error message suggesting to either set the variable or use a custom command).
* Moved environment variable overrides for config fields to mautrix-python.
The new system also allows loading JSON values to enable overriding maps like
`login_shared_secret_map`.

[MSC2409]: https://github.com/matrix-org/matrix-spec-proposals/pull/2409
[MSC3202]: https://github.com/matrix-org/matrix-spec-proposals/pull/3202

* Added handling for rate limit errors when connecting to Instagram.
* Added option to not bridge `m.notice` messages (thanks to [bramenn] in [55]).
* Fixed bridging voice messages to Instagram (broke due to server-side changes).
* Made Instagram message processing synchronous so messages are bridged in order.
* Updated Docker image to Alpine 3.16.
* Enabled appservice ephemeral events by default for new installations.
* Existing bridges can turn it on by enabling `ephemeral_events` and disabling
`sync_with_custom_puppets` in the config, then regenerating the registration
file.
* Added options to make encryption more secure.
* The `encryption` -> `verification_levels` config options can be used to
make the bridge require encrypted messages to come from cross-signed
devices, with trust-on-first-use validation of the cross-signing master
key.
* The `encryption` -> `require` option can be used to make the bridge ignore
any unencrypted messages.
* Key rotation settings can be configured with the `encryption` -> `rotation`
config.
