Update main.lua

Added         SetBlipAlpha(radiusBlip, 100)

 as the radius blip is a solid color, causing potential issues where the blip is over areas of the map that aren't in water and may block visibility. 

The radius is still important as it implies a general area where coral can be harvested.
