Release v0.3.0

Changed the beacon logic to now work within the following logic allowing for passthrough blocks to be placed above beacons.
(if the "beacon" is the same block of the highest point, run function etc you know that)
-Unless the "beacon" is on the same block, go downwards 1 block until either:

-A block the beam can't go through is detected, if so cancel the entire function
-A beacon is found, if so run the function as if it never did the checks

repeat last two steps 1 block down
