Release v0.2.0
With the help of https://github.com/nishaad78 this library will now do monotonic time calculations where supported.
See #18
Also, again with help from https://github.com/nishaad78 the library is a bit faster. We're still on target of 243ns/op for standard snowflake format (allowing us to max out the format) but when using a larger number of bits for sequence number you can get the performance down to around 66ns/op. See #19
Thanks a lot https://github.com/nishaad78 for the help!
