Structs that have characters or unsigned 8-bit ints in them result in a write error

[willzeller]

This struct will results in an error code 5 if you send it to GPMFWriteStreamStore

#define STRUCT_KEY "Ffc"

typedef struct{
    uint32_t test;
    float f;
    char c;
}test_struct_t;

This one runs fine:

#define STRUCT_KEY "Ff"

typedef struct{
    uint32_t test;
    float f;
}test_struct_t;

Structs containing a uint8_t have the same error, I haven't tested with all the possible datatypes.
