Enhancement: Improve offsets for timing judgements

[JackXson-Real]

Currently getting a sick rating feels really luck based for me since it's a little bit off. You are able to click an arrow pretty early and get a sick, but clicking it when the arrow is just a tiny bit above the strumline causes it to be just a good. Even though I play the song perfectly on beat, I somehow manage to almost always get 1 or 2 goods due to this issue. I recommend giving a little more leeway when hitting notes a little bit later so that its the same as hitting a note early. I mainly used Psych Engine to play the game before the update came out, and the judgements for sick rating on there feels more consistent than in base game currently. The difference between that and base game is like night and day. I highly recommend making it similar to Psych Engine so that getting a golden P rank for songs is a lot less painful and more consistent.
