Replaced server member lists, channel lists, and private channel lists
with dicts. This allows O(1) lookups and removes (previously it would be
an O(N) operation to lookup or remove). I did pretty extensive testing
and benchmarking to compare the performance of using lists vs using
dicts. Iterating through lists to find an item is only faster in the
average case for extremely small lists (less than 3 items). For 100
items, using a dict is about 10 times faster on average (and about 100
times faster for 1000 items). The overhead in dicts is in memory usage
and initial creation time. Creating and populating a dict is about 2 to
3 times slower than creating and appending items to a list. However this
cost is still tiny. For 1000 items this equates to about a 70
microsecond difference (on an i7 CPU) for populating the entire dict.
The memory overhead for a dict (compared to a list) is about 25-60 KB
per 1000 items (can vary depending on dict resizing).
Originally I wanted to use OrderedDicts to presereve order, but in my
testing OrderedDicts have about 6x the memory overhead compared to
normal dicts.
Previously we created a copy of the object and did some strange
iteration over the data and set the attributes that we thought
were valid. This worked back then in v0.1.0 of the library when
it was written, but it no longer works nowadays when we want to
be as future proof as possible.
This should reduce the amount of checks for None if someone doesn't
want a websocket connection. The connection state is instead cleared
rather than reconstructed.
Adds comments and also rewrites the logic in a way that is much easier
to see what is going on. For example you can now easily see that the
port is actually encoded in little endian (which is different from
everything else).
