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)

4 Pin connectors

Many devices have 4-pin connectors: Either a Grove connector or a JST one.

Boards that implement an I2C/UART configuration for such a connector are advised to always implement both. To make it consistent, it's important that the pins are mapped in the same manner:

I2C Pins

Follow the Grove layout:

Black(GND) - Red(5V) - Yellow(SDA) - White(SCL)

I2C Pins

Follow this Grove layout on the MCU board:

Black(GND) - Red(5V) - Yellow(RX) - White(TX)

And this Grove layout on the peripheral:

Black(GND) - Red(5V) - Yellow(TX) - White(RX)
