Release v0.3.0

Added parser funcs for all formats and tests for them.

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!

Release v0.1.0

Main change here is in commit 20ab5dc

Please note that at this point there are several global (non exported) variables that have been deprecated and 3 functions. Be prepared to modify your code should you rely on any of these functions.
