Pattern Matching single and multiple characters in {}

[bill-i-am-code]

When running the code below, I would expect all 4 results to be 1

OSCMessage msg1("/test/{1,16}");
OSCMessage msg2("/test/{16,1}");

int val1 = msg1.fullMatch("/1", 5);
Serial.println(val1);
int val2 = msg1.fullMatch("/16", 5);
Serial.println(val2);
int val3 = msg2.fullMatch("/1", 5);
Serial.println(val3);
int val4 = msg2.fullMatch("/16", 5);
Serial.println(val4);

But the actual output is

1
0
1
1

It is as if because the first character of /1 of /16 has already been matched, the /16 is not matched.
