Resync with forks and cleanup

[NoahSprenger]

This pull request includes several updates to the Cargo.toml files and various Rust source files to improve dependency management and refactor the codebase. The most important changes involve switching dependencies to use Git repositories, refactoring sensor data handling, and adding real-time clock (RTC) integration for message timestamps.

Dependency Management:

• Cargo.toml: Switched stm32h7xx-hal and chrono dependencies to use Git repositories instead of specific versions. [1] [2]

Code Refactoring:

• boards/pressure/src/data_manager.rs, boards/strain/src/data_manager.rs, boards/temperature/src/data_manager.rs: Refactored sensor data handling to use SbgData enum variants instead of SensorData directly.
• boards/pressure/src/main.rs, boards/strain/src/main.rs, boards/temperature/src/main.rs: Added RTC integration for generating timestamps in messages. [1] [2] [3] [4] [5] [6]

Code Cleanup:

• boards/pressure/src/main.rs, boards/strain/src/main.rs, boards/temperature/src/main.rs: Removed unused imports to clean up the codebase.

Identifier Updates:

• boards/pressure/src/types.rs, boards/strain/src/types.rs: Changed COM_ID from Sender to Node to reflect the new naming convention. [1] [2]
