Remove the `SINE_TABLE` array in `MathHelper`

Lithium replaces the sin and cos methods in MathHelper, the only two places that access its SINE_TABLE array. That means that the array is unused after that, however it is still kept in memory.

Suggestion to remove it or at least make it an empty array.

This might cause issues with mods that directly access the field, but I think it is unlikely that any mod does this.

It should be fine to do this
