/**
* A class for generating and deconstructing Twitter snowflakes.
*
* A {@link https://developer.twitter.com/en/docs/twitter-ids Twitter snowflake}
* is a 64-bit unsigned integer with 4 fields that have a fixed epoch value.
*
* If we have a snowflake `266241948824764416` we can represent it as binary:
* ```
* 64 22 17 12 0
* 000000111011000111100001101001000101000000 00001 00000 000000000000
* number of ms since epoch worker pid increment
* ```
