* src/snowflake.erl: Added serialization/deserialization methods.
...
snowflake:serialize/1 and snowflake:deserialize/1 are wrappers around
base64:encode. So from here out we pick base64 as cannonical
serialization format.

* src/snowflake.app.src: Removed the sasl dep.
...
Having sasl around is necessary in RELEASES but apps themselves
probably shouldn't have it be a required app.

* src/snowflake.erl: Ensure uniqueness with sequencing.
...
Previous versions used a random number for the sequence ID ensuring
uniqueness stochastically, but that fails to scale. Sequential IDs
will break if more than 2^12 = 4096 snowflakes are registered in any 1
millisecond (hardware unlikely) while random IDs are virtually assured
to collide after sufficiently many events where 2 snowflakes are
generated in a single millisecond (hardware likely).
