Add support for SpiNorFlash and FS (#30)
The external SPI flash is implemented as a 4MB on the local filesystem.
This allows the FS (littleFS) and settings to work properly.

Remove the simulated `FS.h` and `FS.cpp`, because we can now use
the files from InfiniTime directly as the heavy lifting is done in the simulated
`SpiNorFlash.h` and cpp files.

`SpiNorFlash.h` provides read and write functions with `uint8_t` buffer, but
`fs::fstream` expects `char` buffer. Use `reinterpret_cast` and check if by
any chance the `char` type on a platform is implemented with more
than one byte. Then the `reinterpret_cast<char *>(buffer)` would change the
meaning of the `size` parameter, which could lead to garbage data.

7194e3e38e SpiNorFlash: use C++ style struct in C++ only header
`SpiNorFlash.h` is a C++ header, but the `Identification` struct is
created in a C style using `typedef struct`. Clang issues a warining
about this discrepancy:

```
In file included from /home/nero/repos/pinetime/InfiniSim/InfiniTime/src/systemtask/SystemTask.cpp:13:
/home/nero/repos/pinetime/InfiniSim/sim/drivers/SpiNorFlash.h:16:21: warning: anonymous non-C-compatible type given name for linkage purposes by typedef declaration; add a tag name here [-Wnon-c-typedef-for-linkage]
      typedef struct __attribute__((packed)) {
                    ^
                     Identification
/home/nero/repos/pinetime/InfiniSim/sim/drivers/SpiNorFlash.h:17:9: note: type is not C-compatible due to this default member initializer
        uint8_t manufacturer = 0;
        ^~~~~~~~~~~~~~~~~~~~
/home/nero/repos/pinetime/InfiniSim/sim/drivers/SpiNorFlash.h:20:9: note: type is given name 'Identification' for linkage purposes by this typedef declaration
      } Identification;
        ^
1 warning generated.
```

The easy fix is to use a C++ style struct.

Same fix as in: https://github.com/InfiniTimeOrg/InfiniTime/pull/1046

bf3a255ca4 Cst816s: scale down SDL mouse coordinates according to MONITOR_ZOOM
The lv_drivers provided monitor driver supports a `MONITOR_ZOOM`-factor
which scales the window by the set factor. This is 'useful when
simulating small screens'.

The zoom can be set as cmake configuration setting `-DMONITOR_ZOOM=1`.

Probably even more usefull for high-dpi screens where 240 pixels is
really tiny.
