GPS refactored (#262)

- Refactored GPS service and HAL: GPS is no longer part of the HAL configuration. You can now add configure new GPS devices from the GPS settings app.
- T-Deck adds a boot hook to check if a GPS configuration exists and adds it when the config is empty.
- Implemented the concept of ObjectFile to read/write arrays of a raw data type (e.g. struct) to disk.
- Implemented more file utils (e.g. to create all directories of a path)
