Correct range checking for location strings during conversion

Minute values in the range [0, 59] are valid if seconds are
present. If seconds are not present then minute values are
valid in the range [0, <60]

Second values are valid in the range [0, <60]

Examples:
50:59:59.99999 is valid
50:59.99999 is valid
50:59.1:1 is not valid
