Increase 'unsolicited' event listener limit

This change increases the max listener limit for the `unsolicited` event
in the `LutronCasetaLeap` class to 75 (the per-bridge device limit)
times the number of configured bridges. Previously, the default limit of
10 was being used, which means only 10 devices could be used.

Fixes #15
