Discrepancy in Error Messages: INT vs UINT out of range

libcyaml: ERROR: Load: INT value out of range: '128'
libcyaml: ERROR: Load: Invalid UINT value: '256'

Thanks I'll fix it later!

Notice that for signed integers, the distinct messages are symptoms of two different error cases:

typedef struct {
    int8_t *bar;
} foo_t;


static const cyaml_schema_field_t schema[] = {
    CYAML_FIELD_INT_PTR("bar", CYAML_FLAG_POINTER_NULL_STR, foo_t, bar)
    CYAML_FIELD_END
};

On my x64 system, "valid INT values" are [- 2^63 … 2^63 - 1] (signed int64_t).
This is due to the underlying conversion of the string to an integer, where the Invalid INT value error indicates that an INT (a word of the target platform?) cannot hold the value.
Since the target field in the foo_t struct is of size 8 bit, the different error message informs the user, that it cannot hold a value outside of [-2^7 … 2^7 - 1]

libcyaml: ERROR: Load: Invalid INT value: '-9223372036854775809' (- 2^63 - 1)
libcyaml: ERROR: Load: INT value out of range: '-9223372036854775808' (- 2^63)
libcyaml: ERROR: Load: INT value out of range: '-129' (- 2^7 - 1)
-128 is ok (- 2^7)
127 is ok (+ 2^7 - 1)
libcyaml: ERROR: Load: INT value out of range: '128' (+ 2^7)
libcyaml: ERROR: Load: INT value out of range: '9223372036854775807' (2^63 - 1)
libcyaml: ERROR: Load: Invalid INT value: '9223372036854775808' (- 2^63)

Please try this: #248 and let me know if it works okay for you!
