Implement the hal functions necessary for utime.ticks_ms() and utime.ticks_us(). This enables much more accurate measurements of time taken in Pycardium (useful for profiling). Please note that the tick counter will reset whenever a new app is loaded. Signed-off-by:

Add a short delay after opening USB-Mode to prevent immediate exit which happened when pressing the select-button for a very short time. Also exit the menu-app after exiting USB-Mode to force a reload and thus immediately display changes in the apps/ folder. Signed-off-by:

The framebuf module provides a framebuffer implementation running purely in MicroPython which will increase drawing performance by a lot. A follow-up change will be necessary to connect this framebuffer implementation to the display API. This commit is implements a part of MR !211.

Rewrite the delay implementation to be more accurate and properly handle incoming MicroPython interrupts (See issue #177). For this, the delay is split into two functions: - systick_delay_precise(): Delay with microsecond accuracy for delays less than 1 ms. - systick_delay_sleep(): Sleep for a potentially very long time, using WFI to put the CPU to sleep. Whenever the CPU wakes up, this function will poll the MicroPython scheduler so it can execute pending interrupts. Ontop, this implementation allows for a future, fast, tick-based monotonic time implementation (e.g. mp_hal_ticks_ms). Signed-off-by:

Using a bare FreeRTOS mutex is deprecated. Replace it with the new `struct mutex`. This should increase stability of the module. In the process of switching, also remove the `EPIC_FAT_STATIC_SEMAPHORE` define as it is no longer needed with the new mutex API. Signed-off-by:

In the current firmware, different locking mechanisms a littered around the code-base. Among them are bare FreeRTOS mutexes and the hw-locks. The callers for these often specify timeouts but don't make much effort in A) picking robust values for the timeout and B) recovering gracefully from a timeout happening. Most of the time, we return -EBUSY to _Python code_. This is really really bad API design. The firmware needs to have enough integrity to ensure these situations can't ever occur. To combat this, add a new locking primitive: The `struct mutex`. The intention is to replace all other locking and synchronization APIs with this one. This will provide one central place to debug any sort of locking issues. The `struct mutex` API is based on a few assumptions about locking. Those are detailed in `Documentation/epicardium/mutex.rst`, which is part of this commit. The most important one is: Locking can **never** fail. By requiring this to be true, we eliminate the need for drivers to contain (often incorrect) logic for dealing with locking fails. This should drastically improve the stability of the firmware in regards to lock-related bugs. This commit does not introduce any functional changes yet. Signed-off-by:
