Minor Update 0.14.2.0 -- Balance, MacOS fix, crash/mousewheel fixes
Update to golang v1.19.4.
Update to ebiten v2.4.15 which fixes some rare crash bugs, a mouse scroll wheel bug, and a MacOS framerate bug.
Fix minimum version on MacOS to only require 10.13, as originally intended.
Squad ease factor was not very fairly calculated for ship combinations of 3 or more ship types -- it now uses a different algorithm to calculate ease factor that should prevent players from hitting sudden walls at certain levels in their run. Thanks HowardTheGrum and JulezMaddin for reporting.
