chore(*): use latest atat, with new urc channel & replace fugit with …

…embassy-time (#83)

* - Update ATAT, and implement the new URC subscriber channels
- Remove `fugit` and replace it with `embassy-time`
- Update `ublox-sockets`, facilitating both of above changes
- Remove unimplemented sms, voice and location service skeletons
- Remove pin generics in favor of a single `CellularConfig` trait with associated types

* Make flowcontrol a bool in config trait, and export config trait

* Use latest atat git rev

* Fix sometimes stuck in infinite loop at AT probing on initialization

* Update CI to use nightly and remove unused workflows
