Optimize asComponentString method

[thibaultmeyer]

The method asComponentString has been rewrite. String.format has been removed and the method was now around 10 times faster.

Benchmarked with a 100K iteration with the following code:

for (int j = 0; j < 3; ++j) {
    startTime = System.currentTimeMillis();
    for (int i = 0; i < 100000; ++i) {
        asComponentString_OLD(data);
    }
    endTime = System.currentTimeMillis();
    LOG.info("asComponentString_OLD -> {}ms", endTime - startTime);
}
for (int j = 0; j < 3; ++j) {
    startTime = System.currentTimeMillis();
    for (int i = 0; i < 100000; ++i) {
        asComponentString_NEW(data);
    }
    endTime = System.currentTimeMillis();
    LOG.info("asComponentString_NEW -> {}ms", endTime - startTime);
}

Thanks!

@charithe, Any chance to have the new version published on Maven repository (like the version 1.0.0 - http://mvnrepository.com/artifact/com.github.charithe/flake4j) ?

Maybe it could be nice to edit README to specify that your implementation generate a 128 bits Flake ID.

Sincerely.

Done. Released version 1.0.1.
